Northern Irish band Snow Patrol have supported efforts to help locate missing man, Robert Holmes (42).
Mr Holmes was last seen in the Lakeview Avenue area of Newtownabbey shortly after 12.50pm on Wednesday, October 17.
Calling for his safe return on social media, the group said: “Our friend Robert Holmes has been missing since Wednesday. Last seen in the Mossley area of Belfast. If anyone has any information, please call 101 or 999.”
Urging anyone with information about Robert to contact the police, local comedian Jake O’Kane said: “I know Robert, he’s an absolute gentleman. My thoughts are with his family at this time and I hope he’s home soon. If you’ve seen him please do contact the police.”

He was believed to have been wearing a dark, waterproof coat, a grey/black hooded top and a green beanie style hat.
Superintendent Darrin Jones said: “It is one week since Robert was reported missing, and his family and friends are extremely worried about him. They’re desperate to know where their loved one is, and if he is safe and well.
“Robert if you read or hear this appeal, please get in touch with your family or with us.
“I would also appeal to anyone who has seen Robert, or knows of his current whereabouts, to please make contact with police by calling 101, quoting reference number 557 17/10/18.”
