Ten people were detained during the clashes between police and demonstrators on Saturday.
There was initially no information on the number of protesters hurt, while arrest warrants have been issued against two people.
The protests were directed against the eviction of the Askatasuna cultural centre, which has been a meeting place for Turin’s left-wing scene for decades.
The facility was closed shortly before Christmas.
An estimated 15,000 people took part in a demonstration through the city centre on Saturday. Numerous Palestinian flags were also on display.
Eventually, riots broke out as stones, Molotov cocktails and other objects were thrown at police from the crowd and rubbish bins were set on fire.
A police van was also set alight as security forces responded with tear gas and water cannon to disperse the crowd.
One demonstrator was taken away with head injuries.
A video shows a police officer lying on the ground being kicked and beaten by masked individuals, including with a hammer.
Quanto accaduto oggi a Torino, durante il corteo degli antagonisti contro lo sgombero dello stabile Askatasuna, è grave e inaccettabile.

Authorities said the 29-year-old male officer sustained serious injuries but is not in critical condition.
The Italian conservative populist government condemned the riots as “an attack on the state” while Prime Minister Giorgia Meloni accused the rioters of attempted homicide.
