One of Scotland Yard's most wanted men has been arrested in Bangladesh in connection with a double murder in 2003.
Police want to question Ayub Khan, 27, in connection with the murder of Amarjit Singh, 52, and his nephew Rajinder Singh, 35.
They were shot dead near the hotel they owned in Forest Gate, east London.
Mr Khan was detained as he was on his way to an airport in the capital Dhaka, Bangladeshi police said.
The Met had offered a reward of £10,000 for information leading to Mr Khan's arrest and conviction.
In 2004 he was placed on Scotland Yard's Most Wanted list. He has been removed since his detention in Bangladesh.
A senior Bangladeshi police official told the BBC that Mr Khan, originally from Chigwell in Essex, arrived in Bangladesh last week to visit a friend in the city of Sylhet.
He said after their preliminary investigation, Mr Khan will be flown to Britain.
A Metropolitan police spokesman confirmed a man believed to be Ayub Khan was arrested in Dhaka and they will seek his formal extradition to the UK.
At the time of the killings, the police said the men may have been shot dead following a row about parking.
