Two police officers are facing criminal charges over claims they illegally arrested a student during protests four years ago.

PC Calvin Lindsay, 30, and PC Andrew Ott, 35, have been summonsed to appear in court next week to face charges of conspiring to pervert the course of justice.

Prosecutors allege that the pair unlawfully arrested a 20-year-old student on 9 December 2010 during tuition fee protests in Westminster.

He was arrested on suspicion of threatening to commit criminal damage but no further action was taken.

Initially the Independent Police Complaints Commission (IPCC) passed a file to prosecutors in February 2012 but the Crown Prosecution Service (CPS) said there was not enough evidence.

After a review of the decision last December, the CPS authorised the IPCC to summons both officers to court.

They are due to appear at Westminster magistrates court on Monday. Ott is also accused of one count of assault causing actual bodily harm.
