JERUSALEM — The parents of American activist Tristan Anderson, who was injured during a West Bank protest, have asked Israel’s Supreme Court to reopen the case against Israeli border police. 

Anderson’s parents on Tuesday asked the Supreme Court to reopen the case, saying that not all of the security forces that were present at the protest were properly investigated, according to Haaretz. The request comes on the third anniversary of Anderson’s injury.

The Justice Ministry had decided that there was no criminal intent on the part of Israel security forces in Anderson’s injury.

Anderson, 38, of Oakland, Calif., was hit in the head with a tear gas canister and went into a coma during a Palestinian protest against the security fence in the West Bank village of Na’alin in March 2009. He has recovered from his injuries.

Demonstrators protest weekly at certain areas along the security fence, including at Na’alin. The protests often turn violent, according to the Israeli military

Occupy Oakland was scheduled to hold a “Connecting Across Occupations” rally on Tuesday that Anderson was scheduled to attend.
