According to a semi-official news source, Iranian police said on Monday that the death of a young woman in detention was a “unfortunate episode” that they do not want to see repeated.

Mahsa Amini, 22, died after falling into a coma after being arrested by morality police in Tehran last week, provoking nationwide protests by Iranians outraged over the treatment of women by security personnel.

Amini became unwell while waiting with other imprisoned women over the weekend, according to police. However, Amini’s father told the pro-reform Emtedad news website on Sunday that his daughter was healthy and fit.

“This occurrence was unpleasant for us, and we hope to never experience such incidents again,” said Greater Tehran Police Commander Hossein Rahimi, according to Fars news agency.

He denied any maltreatment of Amini and denied charges made on social media about the morality police, who enforce tight restrictions forcing women to cover their hair and wear loose-fitting clothing.
