Two police officers involved in the case of a man who died in police custody are still on sick leave a year after the incident.

The news comes as family and friends of Sheku Bayoh prepare to hold a memorial service to mark the anniversary of his death.

Father-of-two Mr Bayoh died after an alleged incident in as yet unexplained circumstances claimed to involve up to nine officers called to a report of a man carrying a knife in Kirkcaldy, Fife.

A female officer was injured in the episode which began at around 7am on May 3 last year.

The Sunday Mail reported the officer, Nicole Short, is still on sick leave while another officer, Alan Paton, was said to have been on sick leave with post-traumatic stress-related illness.

The case is currently under investigation by the Police Investigations and Review Commissioner (Pirc) - the body responsible for probing complaints by members of the public against Police Scotland - and will also be subject to a Fatal Accident Inquiry.

However the Bayoh family have pressed for a wider full public inquiry they say is needed to adequately address issues over the death.

They have asked friends to help celebrate Mr Bayoh's life at Templehall Community Centre, Kirkcaldy, on Sunday May 8.

On the Sunday of Mr Bayoh's funeral last year a memorial service was also held at the Templehall Community Centre as the family lawyer Aamer Anwar and MSP Claire Baker addressed family and friends including Mr Bayoh's mother, Aminita, his brother-in-law Ade Johnson, and partner Collette Bell.

As they await answers it was reported the two officers on sick leave are on full pay.

Ms Short posted pictures on Twitter at Celtic Park on her first day out since the incident.

She said: “It was the first time I’d been out since the incident happened.

“It was a test to see how I would get on and my dad was right beside me.”

In an interview with The Sun, Mr Paton's wife Pamela is quoted as saying that the early stages of the investigation were frightening.

“It was stirred up and turned into a witch-hunt against the officers and it was incredibly scary.

“It was putting me and my family at risk with the amount of bad publicity and inaccurate stories.

“I’ve been ill and my children have also been through hell."

She added: “We are in limbo. It’s the same for Sheku’s family.”

Calum Steele, Scottish Police Federation secretary, said earlier that "given the trauma associated with the event, it is only right and proper that the service looks after the officers in terms of their pay".

A Pirc spokesman said the probe was ongoing and added: “An interim report was submitted to the Crown Office on August 7.

"The Commissioner continues to act on the instructions of the Lord Advocate and a further report will be submitted in due course.

"It would be inappropriate to go into details during a live investigation.”

Assistant Chief Constable Kate Thomson said: “I wish to reassure the community in Kirkcaldy and the public that the Police Service of Scotland, including all the officers involved, are committed to continuing to work with the Crown Office and Pirc to ensure we fully understand the circumstances that led to the death of Sheku Bayoh.”
