A reward of £10,000 has been offered in the hunt for the killer of a father found lying injured in the street.

Darren Adie, 42 was found unconscious in the middle of a street in Kirkcaldy, Fife, last month and died in hospital shortly after.

He was discovered on Tweed Avenue close to its junction with Lawson Street at around 6.45pm on Saturday May 28.

Detectives have launched a murder probe and appealed for a number of people who spoke to Mr Adie on the day of his murder to come forward.

Charity Crimestoppers has now offered up a reward of £10,000 for anyone who provides information which leads to the arrest and conviction of the person or people responsible.

Angela Parker, the charity's national manager for Scotland, said: "The tragic murder of Darren has left his family devastated and wanting answers.

"This is why we are offering a substantial reward for anyone with information to contact Crimestoppers anonymously.

"We don't ask for any personal details, you won't have to speak to the police and you won't have to go to court. Just tell us what you know, not who you are.

"If you have any information, please contact Crimestoppers anonymously on 0800 555111 or through our anonymous online form at www.crimestoppers-uk.org."

Officers from Police Scotland's major investigation team are keen to speak to a number of people who saw or interacted with Mr Adie before his death.

In particular, officers would like to hear from someone known as Kelly, who Mr Adie was shouting to between 6pm and 6.30pm in the Overton Mains area near Overton Road.

A man in his 40s with a balding or shaved head and of heavy build who was wearing a T-shirt and tracksuit bottoms is also thought to have spoken to Mr Adie in passing on Spey Avenue at the junction with Napier Street, Kirkcaldy around 6.45pm.

Other people who are believed to have been in the area and may have seen something are a male and female who were pushing a buggy, possibly a double buggy, on Tweed Avenue walking towards Napier Street.

A man in his late 20s or early 30s, about 6ft and who walked with a limp and was walking with a woman are also believed to have been in the area, as well as a slim-built man wearing a hooded sweatshirt.

Detective chief inspector Raymond Brown said: "We are keen to speak to these individuals. We believe they may have seen Darren and may hold information that, although they may consider insignificant, could prove vital in identifying his killer.

"As such I would urge them to come forward and speak to the police as soon as possible.

"I'm asking them to please contact us on 101, or speak to an officer in the street."
