A man is due in court today in connection with the death of a man in Scotland more than 20 years ago.
The 39-year-old was detained in Londonderry yesterday and taken to Glasgow for questioning.
Twenty-four-year-old Derek Sheerin was found dead in the East End of Glasgow in September 1994.
Officers from the Police Service of Northern Ireland (PSNI) and Police Scotland were involved in the joint arrest operation.
The 39-year-old is due to appear at Glasgow Sheriff Court today.
