A crime charity has put forward a £10,000 reward to anyone who can provide information to help solve the murder of a Greenock dad in front of his own children.

Christopher Nicol was brutally stabbed by an unknown assailant while his two children, aged five and six, watched.

The pair reportedly told officers a "bad man in a mask" attacked their dad, 27, after arriving at the scene.

Crimestoppers has now issued the reward for information given exclusively and anonymously to the charity.

Angela Parker, National Manager for Scotland Crimestoppers, said: “The horrific circumstances of this murder have left Christopher Nicol’s family and friends devastated and shocked the local community."

"For someone to show such violence in front of young children is extremely distressing and a worry to everyone in the area.

"The man involved is clearly dangerous and must be caught before anyone else is harmed.

“We know that some people refuse to speak directly to police and, in this case, may be fearful or have loyalties preventing them from coming forward. Please let me reassure you that if you contact our charity, you will stay 100% anonymous."

She added: "If you pass on your information about this murder to Crimestoppers you may be eligible for a reward of up to £10,000.

"We hope that this will encourage people to come forward and tell us what they know. Your information could make all the difference and help protect the people and communities you care about.”
