A police constable has been dismissed from Essex Police for gross misconduct.
The 39-year-old officer, who was based at Chelmsford police station, was found to have used excessive and unnecessary force, acted in a discreditable way and failed to act "with honesty and integrity".
It follows an incident in Chelmer Village in October 2012 when the constable encountered a group of young people as he attempted to make an arrest on the village green.
During an argument with a 14-year-old boy, the PC held him by the neck and pushed him into a bush.
He later lied during an account of the event.
Assistant Chief Constable Julia Wortley, who made the decision to dismiss the officer, said his conduct had fallen "significantly below" what was expected by Essex Police and allowing him to keep his job would undermine public confidence in the force.
