Amini, 22, died in a Tehran hospital three days after her arrest by the morality police, authorities announced on Sept 16.

The complaint was filed “against the perpetrators of their daughter’s arrest” and the police who spoke with her following her detention, lawyer Saleh Nikbakht said, quoted by ther Isna news agency.

The family has requested “a thorough investigation” into the arrest and the events that led to Amini’s hospitalisation, the lawyer said, urging authorities to release “all videos and photographs” showing her in custody.

The lawyer said the head of the prosecutor’s office “promised the case would be handled carefully and that all our requests would be taken into account”, and that a medical team appointed by Amini’s family would be informed of any developments in the investigation.
