An eight-year-old child has died in the Siberian region of Tyumen after falling into a sinkhole on school grounds, investigators said Wednesday.

The regional branch of the Investigative Committee said it had opened a criminal case on charges of negligent homicide after the boy’s body was recovered from the sinkhole in the village of Vikulovo.

A local news outlet cited the governor’s press service as saying that the school was evacuated and the site has been cordoned off.
