One man was arrested after the attack in the Edgbaston area of Birmingham, central England, just after 7:00 p.m. (1900 GMT) on Monday.

It came after an 82-year-old man was set on fire outside a mosque in the Ealing area of west London on the evening of February 27.

The Birmingham force said it was aware of the previous attack.

“We are working with the Metropolitan Police Service to see whether they are linked,” a spokesman said.

West Midlands Police chief superintendent Richard North said counter-terrorism police were supporting the investigation.

They had “access to specialist capabilities to help establish the full circumstances,” he added.

In the latest attack, it is thought the victim, who was walking home from a nearby mosque, was sprayed with an unknown substance then had his jacket set on fire.

He suffered burns to his face and was taken to hospital with serious but not life-threatening injuries.
