A woman has been detained four days after she allegedly left parts of a pig both within and outside a newly opened Muslim centre in Warsaw.
Police have confirmed that the 29-year-old suspect was arrested in the capital on Wednesday, and that she may be charged with offending religious sensibilities.
Surveillance footage from the Centre of Muslim Culture recorded a woman wearing sun glasses and white trainers entering the site on Saturday 11 July.
She apparently left a pig's head in the car park and another body part within the centre.
The institution, which includes a mosque, was opened on 6 July in Warsaw's Ochota district.
The consumption of pork is forbidden by Islamic teaching.
About 25,000 Muslims live in Poland at present. The centre provides the headquarters of the Muslim League of the Polish Republic. Arabic language courses as well as courses on Islamic culture are due to held within the complex.
