The Argus today went inside the home of anarchists accused of plotting to disrupt next week's Labour Party conference.

A catapult hung from a wall and rooms were strewn with anti-establishment leaflets and posters.

A Palestinian flag lay screwed up on a bedroom floor, alongside a leaflet entitled Insurrection and Anarchism.

Another had the words "We don't vote with ballots" above pictures of two pistols with silencers.

Police believe the anarchists were planning to take part in a demonstration on Sunday by the Trade Justice Movement, campaigning for worldwide fair trade.

A police spokeswoman said: "We found a poster about petrol bombs but we do not believe these people were planning anything serious.

"We believe they are amateurs and we are not unduly concerned."

Police raided the house in Upper Lewes Road, Brighton, on Tuesday after a call from the owner who lets the property.

Three men were arrested on suspicion of burglary and were held for questioning for a day before being released on bail.

Detectives involved with Operation Otter, the £2.4 million security plan to protect Prime Minister Tony Blair and Labour delegates, were informed of the discovery and arrests.

Officers spent seven hours searching the three-bedroom property and left with several box-loads of material.

Officers were overheard chatting about "bomb-making instructions" but a police spokesman said no explosives or detonators were discovered.

A police spokeswoman said: "There were posters and leaflets relating to possible disruption of the conference."

Literature left behind by police was strewn on beds and floors.

Armed police were stopping and searching cars along nearby Lewes Road as The Argus was taken on a tour of rooms in the house.

The owner said: "I took a cursory look at some of the leaflets before police took them away and saw one that looked-like bomb-making instructions."

Rooms were typical of those occupied by many students, littered with books, videos and clothes. Pants and socks were soaking in a bucket in one bedroom.

There were also college books and folders with students' politics work inside.

A postcard had been written to a friend: "Heard you were on a prison ship. Hope some pirates rescue you and make sure the screws walk the plank."

A photograph showed a bare-chested man carrying an anarchist flag.

The house owner, who did not want to be identified, was angry with police for not keeping him informed of developments but he saved his main criticism for the Government.

He said: "They give squatters rights to move in and stay in people's homes. I pay council tax for this property yet these people are given more rights than me.

"I hope they stick this in their pipe at the Labour conference next week and smoke it."
