Animal rights campaigners took their protest out of the city centre in their latest demonstration against Oxford University's research lab.

About 50 protesters gathered in Banbury Road, Summertown, on Saturday afternoon.

The protesters congregated opposite Ewert Place, which is home to Isis Innovation, a subsidiary of Oxford University.

Scores of police officers and university security guards were at the peaceful demonstration, which lasted more than an hour.

Helen Nicholas, a member of Speak, had travelled from Cirencester to attend the protest against the £18m biomedical lab being built in South Parks Road. She said: "Oxford University cannot be allowed to carry on building its research lab. It is important we raise public awareness about what is going on in Oxford."

Fifteen-year-old Martin Rayment travelled from Leicester with his mother to attend. He said: "What the university is doing is wrong and we want to make as many people aware of this as possible. That's what this is all about."

At the last Saturday demonstration in July, four people were arrested when Speak campaigners attempted to stage a rally in the city centre.

Thames Valley Police made an 11th hour decision to invoke a ban under Section 14 of the Public Order Act, preventing the demonstration from taking place in the city centre.

Protesters staged a rally in Keble Road instead.
