A man who became the first in the county to be named and shamed in a poster campaign about his Asbo has been banned from more areas of Oxford.

Posters of Ian Joseph, of no fixed address, were put up around Oxford city centre and in Cowley two years ago when he received an Antisocial Behaviour Order for making obscene phone calls to council staff.

Now Oxford magistrates have imposed a variation to the Asbo, imposed in November 2004, banning him from Crescent Road and Junction Road and from Salesian House in Cowley.

The court heard on Monday that Joseph had been causing harassment, alarm and distress, said Oxford City Council spokesman Louisa Dean.

He was previously banned from Temple Cowley swimming pool and the council's main reception area at the Town Hall in St Aldate's.

The posters were put up in those areas to help people identify if he was breaching his order.

The new Asbo, brought to court by the council's crime and nuisance action team (Canact) will last two years until November 5, 2008.

Peta Donaghy, Canact team manager, said: "Oxford City Council is pleased with the new order as the residents in the banned areas will be able to stop living in fear from his harassing behaviour.

"The order also prevents him from being abusive to city council staff and the staff of Salesian House. He is also prevented from contacting witnesses who bravely appeared in court in support of our application."

Joseph was issued with the original Asbo two years ago for sending council staff sexually explicit material and making obscene phone calls.

He was also accused of being threatening towards workers in the reception area of Oxford Town Hall.

The Asbo was the third sought by the council to protect staff.

Failure to comply with the variations to the Asbo could land Joseph in prison for up to five years.

He was jailed in September last year for 15 months for attacking a man with garden shears.

After the posters appeared in December 2004, Joseph complained that he felt he was a "victim of the system".
