Police believe key witnesses could hold "vital information" to help a murder investigation into the death of a father-of-two in Fife.

Darren Adie, 42 was found unconscious on Tweed Avenue, Kirkcaldy, close to its junction with Lawson Street at around 6.45pm on Saturday May 28 and later died in hospital.

Officers from the 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."
