Jed Foster, the man accused of murdering PC Andrew Harper, is yet to enter his plea and will face trial in January.
PC Harper died last Thursday in Berkshire while investigating a burglary. The Thames Valley Police officer was dragged under a vehicle and possibly hit by a police car.
Foster’s lawyer Rob Jaques said he “denies any involvement in the horrific murder of PC Harper” and has urged members of the public to come forward with information.
The 20-year-old appeared in court via video-link from Woodhill prison and was supported in the courtroom by friends and family members. PC Harper’s family were also in attendance.
Foster was one of 10 men and boys aged between 13 and 30 who were arrested soon after the officer’s death.
Only he has been charged, while the remaining suspects have been bailed until September 13.
Judge Paul Dugdale has set a trial date of January 20, and expects it will last around three weeks.
Meanwhile, police officers across the UK said they have received gifts from the public thanking them for their service following PC Harper’s death.
Huntingdonshire Police said they were handed a packet of doughnuts while at a protest to “thank us for our work”.
Darlington D Relief Response Officers said they were given a card and a box of chocolates by a member of the public.
An Erdington resident planted two rose bushes at Sutton Coldfield Police Station in memory of PC Harper.
