A body recovered from the River Foyle has been identified as missing Dublin teenager Kieran McKeon.
McKeon disappeared in March along with friend Alexandra O'Brien whose body was recovered from the river on the evening she disappeared.
Described as "vulnerable" Ms O'Brien had travelled to Derry the day after she checked out of hospital in Dublin.
Mr McKeon's body was recovered by a Foyle search and rescue team on Thursday evening.
The PSNI confirmed that a post-mortem examination on remains pulled from the river on Thursday night have been identified as that of Mr McKeon.
"Kieran's family have thanked the PSNI, Foyle Search and Rescue and Irish Coastguard for all their assistance," a spokeswoman added.
"His family have asked for privacy at this difficult time."
