Vahidi says the ministry has been “sensitive” about the issue to know whether the victim was assaulted and is waiting for the final opinion of legal medicine experts on the cause of her death.
He added that investigations also show a physicist had immediately attended the victim at Ershad judicial complex and she was taken to the closest hospital, where she received routine medical care.
The minister also said investigations are underway into whether there has been a “mistake”, or any illegal process, that led to the death of the 22-year-old.
He said a final announcement on the issue will be made after the investigations are concluded.
Amini fell into a coma while in custody in Tehran after being arrested by officers enforcing Hijab rules, known as “morality police,” on charge of failure to properly observe the mandatory Islamic dress code.
She later died in Kasra hospital with her death triggering a social media storm and massive outcry.
Authorities have released footage that shows the woman fall and faint when speaking with a female personnel member at Ershad judicial complex.
Police say Amini had a heart attack and collapsed.
But this is disputed by her family and many others in public, who say the young woman was mistreated while in custody.
