Kasaragod (Kerala) | The post-mortem examination found no injury marks in the body of a man who died at Kasaragod Sub Jail and subsequently a detailed probe has been initiated, police said on Thursday.

The deceased, Muhammad Mubasheer, 29, a resident of Deli here, was found unconscious inside the jail on Wednesday.

He had been remanded in a POCSO case and was shifted to Kasaragod District Hospital, where he died later.

Following allegations by his family that Mubasheer was subjected to torture in jail, the post-mortem was conducted at Kannur Government Medical College.

A police officer said the autopsy did not reveal injuries that could have caused the death.

Internal organs have been sent for further forensic analysis to determine the exact cause.

A case of unnatural death has been registered, and the body has been handed over to relatives.
