A headmaster struggled with police on the ground for more than 30 minutes as they tried to arrest him for harassing a female teacher.

Gregory Hill was repeatedly told by officers to sit up or stand while he kept screaming that he was being assaulted, body-worn camera footage shown to a court revealed.

Hill is on trial for harassment, obstructing police and resisting arrest. He denies the charges.

The arrest was made at Howard Junior School in King's Lynn, of which he was then the head on March 6, 2023.

Footage shown at Lynn magistrates court, on the second day of Hill's trial, shows two female officers approach him as he arrives for work.

PC Heidi Hollington informs him an allegation has been made, which they need to discuss with him.

Hill, 48, of Valley View, Fakenham, replies: "I haven't stalked anyone - I need to go inside and call my union."

As officers begin to restrain him, one says: "You are already under arrest, calm yourself down."

As more officers arrive, Hill shouts: "You've assaulted me, I haven't done anything wrong. 

"You don't have to humiliate me in front of my school, you've done my job in."

A struggle continues on the ground for more than 30 minutes, Hill repeatedly accuses officers of assaulting him and demands to be admitted to hospital claiming he has been "terribly assaulted".

Under cross examination PC Hollington and PC Laura Wild, who were sent to arrest Hill, were asked by Mathew Dance, for the defence, whether his client had been assaulted by heavy-handed officers. Both strongly disagreed.

Hill left the court after appearing to suffer a panic attack as prosecutor Monali Raleraskar began playing the footage to district judge Williams, who is overseeing the trial.

Earlier, the woman in her 20s Hill is alleged to have harassed, was cross examined about exchanges on social media between the two.

Hill is accused of bombarding her with unwanted messages and making derogatory comments about her sexuality.

The woman was asked whether she thought replying to Tweets with hearts and kisses might have encouraged his advances.

"I react to a lot of messages with a heart," she said.

Her mother also gave evidence, saying Hill's repeated contact had caused her anxiety

The trial continues.
