An activist organisation is accusing the police of brutality after arrests were made at a protest in Lyttelton.
Approximately 60 people took part in the pro-Palestine protest at Lyttelton Port on Tuesday afternoon, and police said four people were arrested about 1pm after blocking traffic.
Protesters had blocked a tunnel and poured a liquid onto the road, a police spokesperson said.
Charges were being considered.
