HUNDREDS of mourners are expected to attend the funeral of PC Andrew Harper who was killed on duty.

The 28-year-old officer, died from multiple injuries when he was dragged under a van on a road near Sulhamstead, in West Berkshire, on Thursday, August 15.

A private funeral service for friends and family will be held at Oxford's Christ Church Cathedral at 11:00am.

Thames Valley Police said members of the public were welcome to pay their respects along the processional route.

PC Harper, who married wife Lissie just a month weeks before his death, was killed on the A4 Bath Road while investigating a reported break-in.

Mrs Harper said her husband, from Wallingford, Oxfordshire, was the "kindest, loveliest, most selfless person you will ever meet".

The force said its flags would be flying at half-mast as a mark of respect to PC Harper.

It added on Twitter: "Today is going to be a tough day for all our officers, staff and volunteers as we pay tribute to our fallen colleague."

Those travelling in Oxford are advised to that certain roads will be closed. The Plain, Magdalen Bridge, High Street and St Aldate's were shut at 8am ahead of the funeral service.

Disruption for motorists is expected to last until 12:30.
