Convicted murderer William Kerr - who was wanted for emergency recall to prison - was arrested in Waterloo on Friday, according to North Yorkshire Police.
William Kerr, aged 53, absconded from an approved premises (bail hostel) in Hull on 26 March, which was a breach of his licence conditions and led to a nationwide search to trace him led by North Yorkshire Police.
Following an appeal on the BBC's Crimewatch programme on Thursday this week, officers received information which led them to the Waterloo area of London.
Kerr was arrested in the street at around 7pm on Friday after being spotted by detectives from North Yorkshire Police who were accompanied by the Metropolitan Police officers.
Detective Inspector Eamonn Clarke of North Yorkshire Police said: "Thanks to some information received following the Crimewatch appeal and some further information passed to Crimestoppers we were able to track Kerr to a specific area of London.
"The information was vital to the effort to trace Kerr as he indicated when he was arrested that he was about to leave the London area after seeing himself on Crimewatch. I would like to take this opportunity to thank the people who came forward.
"I would also like to thank the Metropolitan Police for the assistance they have given us in our efforts to locate Kerr."
