Police are to monitor a Bradford concert by a reggae star who is being investigated for alleged homophobic incitement.

Lesbian and gay supporters are planning a major demonstration outside the Town and Country Club when Sizzla performs there this week.

The Metropolitan Police and Crown Prosecution Service are investigating the lyrics of a number of reggae singers, including Sizzla.

A Met Police spokesman confirmed: "The Racial and Violent Crime Task Force has been investigating a number of allegations of homophobic incitement. These cases are now subject to a CPS review."

The singer is performing at the Manningham Lane venue on Thursday.

It is alleged at one concert in Chicago he told the audience to "shoot and kill" homosexuals.

The Bradford Lesbian, Gay and Bisexual Strategic Partnership and gay support group Yorkshire MESMAC are both demanding police take action to cancel the Bradford concert. Tom Doyle, of MESMAC, said: "The fact that someone is willing to put peoples' lives in real danger is sickening. Artists such as this actively encourage hate crimes and help create a climate of fear and intimidation.

"The last thing the people of Bradford need is an homophobic outsider causing trouble in our city. We expect there will be a major demonstration outside the Town and Country Club by lesbian and gay people and their supporters."

Bradford councillor, Reverend Paul Flowers, said: "It is deeply regrettable that this singer is being given a hearing anywhere in the UK, but especially in Bradford.

"We are working hard at social cohesion in this city and the last thing we want is a racist and homophobic singer stirring up trouble.

"The management of the club must now cancel. If they don't I very much hope the Chief Constable will use his new powers to see that this concert doesn't happen."

A spokesman for West Yorkshire Police said: "We have been assured by the organisers of the event that the artist has signed a contract stating he will not commit any criminal acts during the concert. If he does, it will be investigated.

"We will be monitoring the event and will police it as appropriate."

Paul Mastrantuono, manager of the Town and Country Club, said the concert had been put on through a third party and the club was contractually obliged to go ahead with it.

He said: "We wouldn't have taken the show on if we'd known the circumstances as we do now. It's very unfortunate. We don't want to upset people. We are not anti-gay, we have three gays who work for us."
