Police said they are attempting to determine the motives behind an apparent arson attack at an Islamic centre in Harlow, Essex.
Chief Inspector Ed Wells said:
Detectives are investigating this concerning incident and there will be a significant police presence throughout the day to reassure all local residents as we seek to identify those responsible.
We are appalled at the criminal behaviour of the individuals who last night tried to set fire to this building.
They appear to have set fire to foam at one of the centre's doors which has damaged the wall, but thankfully not taken hold of the building.
