Angela and Kyle Harris both attacked a police officer

Angela Harris, 41, from Cardiff, and her three sons all admitted violent disorder in relation to the attack.

Kyle Harris, 15, who butted the policewoman as he was arrested, was sent to a youth detention centre for eight months.

Ryan, 22, and Marcus, 19, were given 120-hour community punishment orders.

Two police officers - Dc Jenny Coleman and Pc Matthew Peterson - had arrived at the family's home in Fairwater, Cardiff, to arrest Kyle on violence charges, Cardiff Crown Court heard.

"The officers cautioned and cuffed him, whereupon Angela Harris screamed abuse, pulled Dc Coleman's hair and punched her in the face," said Layton Hughes, prosecuting.

You started the abuse and you encourage your children to behave in the same way Judge Stephen Hopkins to Angela Harris

Harris' two older sons then joined in the attack.

Mr Hughes told the court: "Marcus Harris pulled the officers back by her clothes, allowing his mother once again to grab her hair and punch her in the face.

"Ryan Harris then attacked Pc Peterson, who was trying to get help on his radio, hitting his hand and trying to get hold of his baton."

Kyle Harris head butted Pc Coleman in the face so hard there was an "audible crack" and she bled profusely.

Sentencing Kyle Harris, Judge Stephen Hopkins branded him a "15-year-old thug" and ruled he could be named despite his age.

"Dc Coleman all but lost consciousness when you head butted her," he told the teenager.

He told Angela Harris she had to take the "lion's share of the blame".

"You started the abuse and you encourage your children to behave in the same way," Judge Hopkins said.
