Reports that Armita Geravand, 16, is in a coma after assaulted by the regime in Iran's morality police •

Garawand was attacked at a underground station in Tehran on Sunday, Hengaw said, adding that she incurred severe injuries. She was being treated under tight security at Tehran's Fajr hospital, the group added.

"There are currently no visits allowed for the victim, not even from her family," it said.

Hengaw said the teenager hails from the Kurdish-populated city of Kermanshah in western Iran. She does however live in Tehran.

A female local journalist who tried to visit the hospital, Maryam Lotfi, was briefly detained, Hengaw added.

Armita Geravand's case is highly sensitive, raising concerns the 16-year-old might face the same fate as Mahsa Amini, a 22-year-old woman whose death in a coma last year in the custody of morality police sparked months of nationwide protest.

She is in coma at the Intensive Care Unit of the hospital and her condition is critical ... her relatives said there is a heavy presence of plain clothes at the hospital," one of the activists in Iran said
