Detectives investigating the murder of a man in Westminster in 1980 have made an arrest.
On Wednesday, 5 May, a 59-year-old man was arrested at a west London police station on suspicion of murder.
He has been released under investigation in relation to the murder but has been detained under the Mental Health Act.
On 6 June 1980, officers attended a residential property in Kensington Gardens Square, W2 after concerns were raised about the occupant of the address. Anthony Bird, then 41, was found deceased inside the property.
A post-mortem examination confirmed the cause of his death was strangulation.
