Police were chasing the Bomaderry youth on foot when the alleged assault and injury to the 32-year-old female constable happened.

Police went to an address in Samuel Street, Bomaderry about 9am Friday to speak to the youth, who was wanted on a forensic procedure warrant from another area.

Police allege when the youth saw officers arrive, he ran from the area, heading in the direction of Meroo Road.

Police chased the youngster and two extra police cars searched the area, with the youth allegedly attempting to hide in another property in Samuel Street.

Officers found him and as he attempted to jump a fence to avoid arrest he was sprayed with pepper spray.

Police allege the youth also resisted officers as he was placed in the rear of a paddy wagon.

He has been charged with assaulting police and resisting arrest.

Police were also questioning the youngster over in a number of break and enter offences in the Wagga Wagga Local Area Command, for which he was a suspect.

The female officer, who was allegedly assaulted during the pursuit, was taken to Shoalhaven District Hospital for X-rays on what was believed to be a possible broken ankle.
