Police have made an arrest over the dumping of two pigs heads at an Islamic girls school in December.

The incident at the f the Markazul Uloom Girls School in Park Lee Road, Blackburn sparked a' hate crime investigation'.

A Lancashire police spokeswoman said today: "I can confirm that a 28-year-old man from Darwen has been arrested on suspicion of racially-aggravated provocation and has been bailed until February 16."

The previous week graffiti painted on the school wall reading 'no mosque' had to be removed.

Police said at the time that one pig's head was found at the school gates and the other thrown over them.

Officers began an investigation and treated the incident as a 'possibly racially or religiously motivated' crime.

The incident followed a controversial planning application been submitted to build a mosque with dome and minarets, at the school which has generated an online protest petition with almost 2,000 signatures.
