Police in London appealing for information to trace missing 18-year-old student Patrick Halpin have found a body.
"The body was discovered at approximately 19:50hrs today, Thursday, 6 February, in an enclosed area in the vicinity of Burger King and the Zoo Bar off Leicester Square, W1," a police statement said.
"Enquiries are underway to establish the identity of the deceased."
Patrick was last seen shortly after midnight on Wednesday when he left the Zoo Bar in Bear Street, Leicester Square, in central London.
The teenager was visiting the UK capital on a trip with DCU Drama Society.
His sister, Regina Ni hAilpin, earlier issued an appeal on Facebook to help find her brother.
She wrote: “(Patrick) was in London on a trip this week and went missing from a nightclub last night and hasn’t been seen since.
“He was in The Zoo nightclub just of Leicester Square and left to go to Burger King but did not return home. He should have been staying in the Astor Museum Hostel, Bloomsbury, London.”
A later post appealed for help in carrying out a search: “Hey everybody, this is Regina’s friend posting on behalf of the family. We really appreciate all your messages and offers of support, we plan to carry out a search tonight if anyone in the London area is available.”
