A BOY who briefly left school grounds to wave goodbye to his parents was allegedly beaten to death by teachers as a punishment.

The family of Year 6 student Shamim Mullick said staff at Al Islamia Mission School in Majlishpur, India inflicted fatal injuries on the 13-year-old.

Police this week confirmed they have arrested the school’s owner and principal as part of a murder investigation.

“Headmaster Hanif Sheikh and school’s owner Shahzada Al Mamun alias Liton Sheikh have been arrested after a complaint was lodged at Barwan police station,” Superintendent of Police Murshidabad, C Sudhakar, said.

Shamim’s parents had reportedly visited their only child at the private residential school before leaving to return home on Monday morning.

Shamim reportedly left his parents at the school gate before turning around and crossing the school boundary to give them one more wave goodbye.

When Shamim returned to the campus, Sheikh was allegedly furious that the teen hadn’t sought permission to leave, and allegedly attacked Shamim.

Shamim was taken to a nearby nursing home, which — along with the school — is owned by Sheikh, but it wasn’t until his condition deteriorated further that he rushed to a nearby government hospital that night.

Doctors declared him dead on arrival.

Shamim’s devastated parents said they first heard about their son’s fate when they got a call from the school at midnight to say he was dead.

The Indian Express reported that Shamim’s father Jugnu said: “We were not even informed by the school. This despite the fact that my cellphone number is registered with the school. At around midnight, I got a call from the hospital that my son has died. When I called up the school authorities, they told me that our son had fallen sick while studying.

“It was later from the hospital and other sources that we came to know that our son was beaten up mercilessly by the headmaster.”

Jugnu said the school initially tried to claim that the boy had simply fallen ill while studying — but the hospital confirmed he’d died as a result of a savage beating.

Shamim’s parents claim they were later told that the beating had been carried out by Sheikh.

They made a formal complaint to police who arrested Sheikh and the school’s owner Mamun.

The pair are on remand.
