A REWARD of up to £10,000 is being offered to anyone who can help catch the killer of murdered Greenock dad Christopher Nicol.

Charity Crimestoppers is offering the cash in exchange for information that can solve the brutal murder.

The 27-year-old was stabbed to death in his own home in Maple Road in Greenock in the presence of his two young children on September 26.

A masked man pushed his way into the flat and knifed him several times.

This sparked a massive police manhunt but police are still looking for a breakthrough.

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 per cent anonymous.

“Crimestoppers has been around for over 31 years and we have helped millions of people to speak up anonymously.

"If you have information, you can call our UK Contact Centre 24/7 on 0800 555 111 or use our simple anonymous online form at Crimestoppers-uk.org.

"We don’t judge, we won’t ask for your name or personal details.

"Just tell us what you know and then you’re done.

“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.”

The Telegraph spoke exclusively to Christopher's mum Karen last week, when she revealed her anguish at being unable to bury her son until his killer is caught.

She told the Telegraph: "My heart has been totally ripped out.

"As soon as I close my eyes, the tears start streaming down my face.

"I miss him so much."

Even worse is the impact the brutal murder has left on her grandchildren Darren, five, and six-year-old Amylynn, who were in the house at the time.

She said: "It breaks my heart when the kids keep asking if their daddy is coming back."

Karen, 52, says she is begging someone to come forward with information to get justice for her son.

She said: "I visited Christopher in the mortuary and I promised I would find the man who killed him.

"He needs to be taken off the streets before it happens to someone else.

"It only takes one person to come forward."
