Two men have been arrested in Scotland over the rape and murder of a young mother during a night out in a loyalist club in Northern Ireland 30 years ago.

Detectives investigating the killing of Lorraine McCausland have detained two men, aged 49 and 56, in Scotland and a third suspect, aged 53, in England.

The mother-of-two, aged 23, was found beaten to death beside a stream in Forth River, north Belfast, in the early hours of March 8, 1987.

She had been on a night out and was last seen in a nearby loyalist club at Tyndale.

The case was reopened last year after detectives identified "potential new lines of inquiry".

Fourteen arrests were made during the original police investigation but no one was charged.

Members of the paramilitary Ulster Defence Association were suspected of raping Ms McCausland in the club before "savagely" beating her and dumping her body.

Police believe witnesses have long been fearful of coming forward due to the involvement of the violent group.

Ms McCausland's son, Craig, was murdered in north Belfast in 2005 during a spate of killings linked to a loyalist paramilitary feud.

The three men arrested on Wednesday will be transported to Northern Ireland for questioning.
