Concern is growing for a 12-year-old boy and a 15-year-old girl who have been missing for three days.

Friends Jake Slessor and Shiona Homer were last seen in Ayrshire on Sunday afternoon.

The last sighting of Jake was at James Crescent, Irvine, at around 12.45pm, while Shiona was last spotted at Nelson Road, Saltcoats, at around 2.50pm.

Jake was wearing a black tracksuit, white T-shirt and blue trainers when he went missing. He is 4ft 8in with fair hair.

Shiona was last seen wearing blue jeans, a white top and navy cardigan. She is 5ft 5in, of slim build with collar length brown hair.

Inspector Colin Convery said: "Jake and Shiona are friends and have both gone missing before, however, given their age and the length of time they've been away, concern is growing for their welfare.

"Both are known to spend time in the Irvine, Ardrossan, Saltcoats and Largs areas and I would appeal to anyone with information on their whereabouts to get in touch with officers via 101.

"I would also appeal directly to Jake and Shiona to please make contact with someone to let us know they are safe."
