Around 300 people have taken part in a march in support of the family of Sheku Bayoh as they prepare to meet Police Scotland's chief constable for the first time since his death in police custody.

Father-of-two Mr Bayoh, 31, died after being restrained by officers responding to a call in Kirkcaldy on May 3.

His partner Collette Bell and relatives joined hundreds of people on a march through the Fife town today.

Family solicitor Aamer Anwar said the support showed that their campaign for justice is not going away and they plan to take it to Holyrood, Westminster, party political conferences and trade union meetings across the country.

The Police Investigations and Review Commissioner (Pirc) is investigating the circumstances of the death.

A post-mortem examination proved inconclusive and his family have raised concerns that experts called in by investigators may blame a medical condition known as excited delirium, which has been cited in other custody deaths.

It is used to describe the state of a person who, as a result of mental illness or drug use, becomes agitated, violent and displays extreme strength.

Mr Bayoh's family will meet Police Scotland Chief Constable Sir Stephen House tomorrow for the first time to raise concerns over the death and subsequent investigation.

Sir Stephen has previously faced criticism for not meeting the family in the four months since his death. Last month he announced he is stepping down from his role later this year.

Mr Anwar said: "I would hope that the meeting will be positive, I expect it to be a very robust one.

"The family do welcome the fact that the Chief Constable, despite announcing his resignation, has had the courage to say that he will meet the family.

"It's an important step forward and the family want the chief constable to see what they have been through and to raise concerns.

"In a few weeks time there will be a new chief constable. I understand there will be other senior officers in the meeting, it may be that one of them will be the next chief constable and the family want them to know that they are not going away and they hope Police Scotland learn lessons from the death of Sheku Bayoh.

"Fundamentally they want to see accountability and the want to see justice."

Last week, the family met the lead Pirc investigator and called for ''results rather then broken promises".

The Pirc said that all lines of inquiry are being explored to establish the circumstances of trainee gas engineer Mr Bayoh's death.

Police Scotland said they await the conclusion of the Pirc investigation and remain committed to co-operating fully with the body's inquiries.
