Three men were arrested on suspicion of manslaughter on Wednesday as part of an investigation into an explosion that shattered a building in Leicester (central England) on Sunday night, claiming the lives of five people, police.

The three men, all in their thirties, were arrested in the late afternoon and “interrogated by investigators,” said Leicestershire police.

“A man comes from East Anglia, the second from the north-west of the country and the third from the East Midlands,” police said, adding that no other details will be released.

The police are asking “the media and the public not to speculate on the identity of those arrested, the circumstances that may have led to their arrest and the cause of the explosion” and said that they have “no evidence that the events of Sunday night are somehow related to terrorism.

A 46-year-old mother and two of her children, aged 17 and 18, died in the blast, followed by a fire that ravaged the building. The family lived in an apartment above a business.

The girlfriend of one of the 18-year-old sons and a 22-year-old shop assistant on the ground floor also lost their lives.

Five people were further injured in the incident
