A man was injured in a shooting incident at a house in Derry yesterday evening.
The incident took place at a residential premises in the Cromore Gardens area in Derry.
The man was brought to hospital after suffering gunshot wounds to both knees.
Police condemned the shooting, saying that it was an "abhorrent" thing to do.
"This is the time of year for carefree celebration, a time for family and children. Yet here we are with another person in hospital getting ready to go into surgery as a result of the actions of mindless thugs," said Detective Inspector Bob Blemmings.
"It is absolutely abhorrent that anyone would go into a busy built up residential area comprising of young families and elderly people with a loaded firearm. The recklessness shown by those involved in carrying out this attack should be condemned. The harm has to end.
"Tonight the excitement and innocence of young children has been violated by those who carried out this shooting. Instead of Christmas bells ringing in their ears they have the sound of gunshots. No child should ever have to live like this," added Det Insp Blemmings.
"I would appeal to anyone who noticed any suspicious activity in the Cromore Gardens area this evening around 8pm to contact detectives at Strand Road on the non-emergency number 101 quoting reference 1463 21/12/18. Alternatively information can also be provided to Crimestoppers on 0800 555 111, which is 100% anonymous and gives people the power to speak up and stop crime," added the detective.
