Huge searches for Chloe Kinsella, aged 15, were being concentrated along the banks of the Shannon, near her home in Kileely, on the north side of the city.
Supt Daniel Keane, Henry Street, who is heading the search operation, said: “There is major concern for Chloe. The Limerick Marine Search and Rescue, the Shannon-based coastguard helicopter, voluntary divers and many locals are assisting us in the search.”
Supt Keane said that items of clothing found yesterday did not belong to Chloe.
He said that CCTV images from cameras at Colbert Station had been examined, but showed no trace of the missing girl buying a train or bus ticket.
Other CCTV images from security systems in the Kileely area also failed to yield any new clues.
She is described as 5ft 3in in height, of slim build, with fair hair and blue eyes. When last seen she was wearing a white T-shirt with a skull motif.
Supt Keane said: “Local people have been very good in helping with out search operation and we very much appreciate their assistance. We are still searching a large open area towards the back of the family home at Kenyon Avenue, Kileely, which adjoints the river.”
Chloe left home at around 8.30pm by leaving through a rear bedroom window.
She had been out earlier in the day and had bought a ticket for the One Direction concert due to be held in Dublin next May.
Her family said it was totally out of character for Chloe to leave the house without saying it to her parents, Shirley and Kevin.
