The Lancashire police said on Wednesday they have arrested a man in connection with the case of two pigs' heads being dumped outside an Islamic school in December 2015, in what was seen as a hate crime against Muslims.
On 19 December, the pigs heads were found near the Markazul Uloom boarding school in Blackburn, which the police investigated as a hate crime as pork is considered impure in Islam.
"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," a local police official told Lancashire Telegraph.
In another part of England, a 28-year-old woman from Coventry was arrested on Wednesday on suspicion of terrorism offences linked to Syria, the West Midlands Police said on their website.
The police said the arrest was "pre-planned and intelligence-led".
Earlier in the day, reports that the Lancashire police questioned a 10-year-old Muslim student after he wrote that he lived in a "terrorist house" while intending to say "terraced house" had sparked outrage.
The boy was interviewed by the police last month, and his family has said he was left "scarred".
On Wednesday, British Prime Minister David Cameron had criticised the "backward attitudes" of some Muslim families in the United Kingdom and had urged Muslim women to learn English to better integrate with the country.
