Courts in the Iranian capital of Tehran and surrounding provinces jailed 400 people on Tuesday in connection with recent anti-government protests, The Guardian reported . Described as rioters in official rulings, the convicted demonstrators were handed extreme sentences.

One hundred and sixty people were sentenced to between five and 10 years in prison, 80 people to two to five years and 160 people to up to two years, said Tehrans judiciary chief Ali Alghasi-Mehr, as quoted by the regional Mizan news agency, per The Guardian.

Another 70 people were fined, the BBC reported .

Nationwide protests erupted after 22-year-old Mahsa Amini , who was arrested on Sept. 13 for allegedly failing to properly wear a hijab, died in custody. Witnesses said she had been beaten by officials, spurring outrage against the Islamic Republics religious laws, morality police and treatment of women.

Since then, 490 demonstrators, including 68 children and 62 security personnel, have been killed, Human Rights Activists News Agency reported . Of the more than 18,200 people arrested in relation to these protests, only 3,780 have been publicly identified.

Iranian officials said in early November that 1,024 people in Tehran were charged for anti-government protests. The detained had purportedly committed acts of sabotage including assaulting or martyring the guards and setting fire to public property, officials said.
