Former miners’ union leader Arthur Scargill has written to the Independent Police Complaints Commission to request an investigation into his arrest at Orgreave coke works in 1984.
Mr Scargill’s letter alleges his arrest was planned by senior South Yorkshire Police officers and claims the force kept a ‘conspiracy file’ on him.
The IPCC said it would consider the content of Mr Scargill’s letter.
South Yorkshire Police have not responded.
Mr Scargill was one of 93 people arrested in June 1984, after a confrontation at a British Steel plant near Sheffield between 10,000 striking miners and 5,000 police officers.
In the clash, which became known as the Battle of Orgreave, 51 miners and 72 police officers were injured.
In his IPCC letter, Mr Scargill said his lawyer had ‘accidentally seen a file marked Scargill Conspiracy File’ during a visit to South Yorkshire Police headquarters following his arrest.
The force has referred itself to the IPCC over its conduct around Orgreave.
