A brick attack on the offices of a Northumberland MP, with a note attached warning of a pro-hunt protest, has been dismissed as the actions of a crank.
The brick, with a makeshift leaflet wrapped around it, was thrown through the window of Blyth Valley MP Ronnie Campbell's constituency office.
Mr Campbell admits to being against hunting, but says he has never spoken in any debates on the issue.
The Countryside Alliance denied any responsibility for the incident.
The Labour MP told BBC News there was a similar incident last year, immediately after one of the votes on hunting in Parliament.
But he said he believed the act was that of a disgruntled individual and not of a recognised organisation.
Regional director of the Countryside Alliance, Richard Dodd, said as far as he was aware, no-one from the organisation was involved.
Mr Campbell said: "The leaflet around the brick said there was going to be a protest in Blyth on Saturday.
"I don't know anything about any march or protest and I think this was someone just acting alone.
"But it's obviously someone who believes in fox hunting and who has decided to take revenge on me."
Mr Dodd said: "I know nothing of the brick and nothing of the protest.
"It could have been somebody from the pro-hunting lobby, but it could also be somebody just taking the opportunity to put Ronnie's windows out.
"Unless we have the culprit and I can look up their name, you can't tell who this is."
Mr Campbell says it will cost about £150 to replace the window.
