A 58-year-old man has been arrested in connection with the suspected murder of Anthony Littler almost four decades ago.
Mr Littler was found with fatal head injuries in an alleyway known as The Causeway near East Finchley Tube station in north London. He was found at 12.15am on May 1, 1984.
He had been working as an executive officer at the now-defunct HM Customs and Excise. He was said to be single and lived a short distance away from the tube station.
Earlier this week the Metropolitan Police put out an appeal for information surrounding his death.
On Sunday, a man was arrested on suspicion of murder. He has been bailed until January pending further enquiries.
Detective Chief Inspector Neil John, who is leading the investigation, said: “This arrest comes just four days after our latest appeal, and I would like to thank everyone who has already come forward with information.
“However, we still need to speak with anyone who may have witnessed the events leading up to Anthony’s murder.”
Anyone with information should contact police on 020 8358 0100 or Crimestoppers anonymously on 0800 555 111
