Police urgently need to trace the four men pictured

Police have released CCTV images of the four men involved in the recent failed attacks on London tube stations. They have also given further details of the movements of the men and named two people who they believe are pictured on the CCTV images.

Scotland Yard urge anyone who may know where the suspects were to call 999, or if they could identify any of the men to call the anti-terrorist hotline on 0800 789 321.

Scotland Yard assistant commissioner Andy Hayman warned members of the public not to approach these men under any circumstances.

He said: "These are four men we urgently want to trace in connection with attempts to detonate four explosive devices on the transport system in central London yesterday. Anyone who has information about where these men currently are, you should immediately called 999 and ask for urgent police response."

Raids on London properties are on-going including the former residence of one of the suspected bombers.

Shepherd's Bush Tube Bombing

This picture taken at Westbourne Park Tube shows another man the police wish to contact, this time in connection with the attack at Shepherd's Bush.

The picture was taken at 12.21pm. Police believe he travelled westbound on the Hammersmith and City line to Shepherd's Bush underground where he attempted to detonate a bomb at 12.25pm and then ran from the station. He was wearing a dark shirt and trousers and was later reported to be wearing a white vest.

The Shepherd's Bush suspect is believed to have escaped from the train through an emergency exit and then scaled a fence to get into Macfarlane Road which runs parallel to the tracks. He ran through several back gardens before finding a door that was opened and went through a house and then onto Wood Lane. There he proceeded north towards the BBC centre. At this point he is believed to have discarded his jacket and was wearing a white vest. He was last seen walking northwards under the A40.

The man's escape route appears to be in the direction of Little Wormwood Scrubs where a fifth rucksack was discovered. There is speculation that there may have been a fifth bomber who decided to abort his mission and dump his bomb in the park. Initial forensic examination reveals clear similarities between the four bombs used and this discovery.

The other three men police wish to trace all entered Stockwell underground station just before 12.25pm, last Thursday, 21st July 2005.

Warren Street Tube Bombing

One of the men entered Stockwell underground station at the same time as the others with a small purple rucksack. He tried to set off a bomb on a northbound Victoria line train between Oxford Circus and Warren Street underground stations. Shortly afterwards, at about 12.40pm he was seen without the rucksack in Warren Street station. He then left the booking hall by vaulting over the ticket barrier and running towards the exit.

Police believe this man to be Yasin Hassan Omar aged 24.

Oval Tube Bombing

The man pictured got onto a Northern line northbound train and shortly afterwards attempted to set off a bomb between Stockwell and Oval stations. The train stopped at Oval station and he was then chased from the station by members of the public who tried to detain him. The police have described these people as extraordinarily brave.

He left the Oval station at about 12.35pm and ran along Brixton Road, towards Brixton. He went into Normandy Road, Cowley Road, Gosling Way, where at the junction with Mostyn Gardens, he threw away his top with the New York logo. He then went into Cancell Road, Frederick Crescent and Langton Road. He was last seen at a quarter to one in Tindall Street.

Hackney Bus Bombing

The second man also went into Stockwell underground station. He was seen walking towards the platforms. Police know that at 12.53 he got on a number 26 Bus in the Bank area of the City. He was carrying a grey & black rucksack and sat on a seat towards the back of the bus with the bag next to him. He too tried to set off a bomb. He got off the bus in Hackney Road at about five past one.

Police believe this man to be Muktar Said-Ibrahim, also known as Muktar Mohammed-Said. They believe he was associated with, and has recently visited, 58 Curtis House in Ladderswood Way, London, N11. He is 27 years old and police are in the process of searching a number of address in London including 58 Curtis House.

All five of these bombs had been placed inside dark coloured rucksacks or sports bags. All of them were made using the same type of plastic food storage container. These were manufactured in India, and are exported through one company into this country and then sold in approximately 100 outlets across the United Kingdom. The type police are interested in is this six and a quarter litre sized container with a white plastic lid. It has a label describing it as a "Delta 6250 with Lid", and also has another coloured label with the description "Family Containers, Delta, Superior Quality." They are only interested in the white lid variety. They are also produced in other colours.

Police have appealed to any shop keepers and shop workers who may have sold five or more of these identical food containers in recent months, perhaps to the same customer to come forward.

Sir Ian Blair the Metropolitan Police Commissioner has appealed for witnesses with mobile phone pictures of any of the incidents to send them to www.police.uk.
