A Greenock dad was murdered in front of his own children in his family home, police have revealed.

Detectives revealed the tragic details following the "disappointing" response to an appeal for information following the brutal death of 27-year-old Chris Nicol on Tuesday, September 26.

They say his two young children, aged five and six-years-old, were in the Maple Road flat when the dad was violently attacked.

It's thought Chris' attacker wrongly believed there was a large sum of money in the house and that was the reason behind the attack. 

Officers have now launched a re-appeal for information, adding "the answer to this murder lies in the local community".

Detective Chief Inspector Martin Fergus from the Major Investigation Team said: “Christopher Nicol was within his flat in Maple Road around 9.05pm on Thursday night when he was violently attacked in front of his two young children aged five and six years.  

"Both children are receiving full support from a number of partner agencies at this time.

 "At this time we believe that the motive for this was robbery and that Christopher was targeted specifically because his attacker thought there was a large sum of money in the house which was not the case.

"For whatever the reason, to carry out such a brutal attack in front of such young children is absolutely sickening. It shows an absolute disregard for their safety or suffering.  This callous killer must be caught.

“Although our murder investigation is progressing, we have been disappointed by the public response to our previous appeal. 

"I believe that the answer to this murder lies in the local community and I am in no doubt that there are people out there who have vital information on this incident, who have not yet come forward.  I would urge them to look to their conscience and contact us."

The suspect is described as white, aged betweenn 20 to 30-years-old, with a local accent.

He is approximately 5ft9inches tall, slim build, with an unkempt, reddish, brown beard and moustache. 

He had bad teeth, with some visibly missing.  He was wearing a black beanie hat with a logo, possibly Timberland, black top and black jeans or bottoms.
