West Yorkshire Police say more assaults happen around sporting events, particularly when drink is involved.

A car with a detective and a domestic violence co-ordinator is attending all domestic violence incidents in the city so better evidence can be collected.

Det Ch Insp Chris Thompson said the force wanted to increase the number of offenders taken to court.

'Tough approach'

He said: "We want to send a clear message to offenders that if they are involved in domestic violence we will arrest them, and if we don't arrest them at the time the offence is committed we will continue to look for them until we find them.

"We are also identifying and arresting outstanding domestic violence suspects and prolific offenders and doing bail checks.

"In the run up to, and during the World Cup, we will have extra resources to deal with domestic violence incidents and are taking a tough approach towards offenders in order to improve the quality of life for people living in the district."

Wakefield Police deals with around 500 reports of domestic violence every month, he said.
