Farmer Brian Hagan denied breaching an Asbo

Charges against Brian Hagan, 62, from Briston, Norfolk, were dropped last week because of insufficient evidence.

The Crown Prosecution Service says it does not have the power to enforce a breach of an Asbo.

Police, who were due to apply for a full Asbo, say there is little point obtaining it if it cannot be upheld.

Norfolk Police say they will meet Mr Hagan to try to resolve the situation and look at other ways of protecting the people affected.

The interim order was first granted when the farmer's pigs repeatedly roamed free and damaged neighbouring property.

Mr Hagan had opted for a crown court trial over the claims he breached the terms of his temporary Asbo.

That case was dropped last week.

The case to decide whether Mr Hagan should be made the subject of a full Asbo was due to be heard on Monday at Cromer Magistrates' Court.

It is thought to be the first time an Asbo - introduced to counter unruly behaviour - has been imposed on a farmer in a bid to control his animals.
