Sherwood police dog trials commemorate killed Pc
Annual dog trials to commemorate a police officer killed in the line of duty are being held at a stately home in Nottinghamshire.
In 2003, dog handler Pc Ged Walker was dragged to his death by a stolen taxi as he tried to arrest the driver - convicted robber David Parfitt.
Officers and dogs from Nottinghamshire Police are competing in the Sherwood Forest trials at Thoresby Hall.
Sunday's event is a "fantastic chance" to see dogs in action, the force said.
Pc Walker, 42, had been attempting to stop the taxi in St Albans Road, Bulwell, when he suffered critical head injuries.
Parfitt, a former drug addict, was later convicted of manslaughter and jailed for 13 years.
A memorial stone to the police officer was unveiled on St Albans Road in 2005.
