One of Los Angeles' top cops has filed for a restraining order against a Black Lives Matter activist who has allegedly been stalking him.

The Los Angeles Police Commission Matt M. Johnson alleged Trevor Gerard, a member of the protest group, followed him home and to his office in a complaint filed against the 35-year-old activist.

Johnson, who was appointed commission president in September 2015, went on to allege Gerard, 'mouthed violent threats to Johnson from the audience at board meetings and made threatening statements', according to LA Weekly.

The magazine also said Johnson claimed Gerard made a 'a gratuitous reference' to top cop's children.

The restraining order was filed on December 19, the day after a Black Lives Matter protest was held outside Johnson's home in the leafy suburb of Sherman Oaks.

Two days prior, on December 17, the group managed to make their way inside the offices of a law firm, where Johnson is a managing partner.

Gerard hit back at the allegations, claiming Johnson is trying to spin them for his own political gain.

'I never told him that he should be afraid of me. I never told him to meet me outside. I never threatened him with any kind of physical violence,' he told LA Weekly.

The 35-year-old then blasted the the police commission board, accusing it of contributing to many of the issues Black Lives Matter is protesting against.

'The people who sit on the commission board largely have acted as a rubber-stamp body for the extreme levels of violence that LAPD has been engaging in,' Gerard said.

'They have become too comfortable with the way that we're forced to engage them in that meeting space, which is in the LAPD headquarters itself.'

Gerard is seen speaking during a protest in Los Angeles earlier this year. The 35-year-old denied the allegations against him
