A 77-year-old man arrested on Thursday in Antrim in connection with the investigation into the murder of Gerard Hoarau in London 33 years ago was, on Friday, “released under investigation” the Met Police said.
He had been arrested in connection with the assassination of an exiled Seychelles political leader in London in 1985.
Officers from the Met’s Counter Terrorism Command and the PSNI were involved in the arrest of the 77-year-old man in connection with the investigation into the murder of Gerard Hoarau in Edgware.
A press release on Thursday from the Metropolitan Police said a man was arrested at an address in Antrim at 9.50 that morning on suspicion of conspiracy to murder.
He was detained under the Police and Criminal Evidence Act and transported to a south London police station for questioning.
Officers were also searching an address in Antrim.
On 29 November 1985, Mr Hoarau was shot a number of times with a Sterling sub-machine gun while he was on the doorstep of his home on Greencourt Avenue.
He was the opposition leader in the Seychelles and had been described at the time as “political enemy number one”.
At the time of the attack blame was directed at his political rivals and came during a time great turmoil in the country with many public officials disappearing in suspicious circumstances or being killed.
Reports at the time said he was likely killed by a hired hit man.
Detectives previously arrested a number of individuals in connection with the investigation but no-one was charged with murder.
Three people were convicted in 1986 for perverting the course of justice in relation to the investigation.
A review of the investigation was initiated in 2016 from which fresh lines of enquiry were established, leading to Thursday’s arrest, the Met Police said.
Police said the man arrested on Thursday has not been previously arrested as part of this investigation.
