ALBANY, Ore. (AP) — Police say a third teenager has been arrested in connection with a bias-related assault at an Albany park.

Police said a 16-year-old boy was arrested on Thursday on suspicion of assault, conspiracy to commit assault, bias crime and tampering with a witness, The Albany Democrat-Herald reported.

On April 13, police said a 13-year-old boy was assaulted by four 16-year-old boys and a 15-year-old girl. One boy and girl were previously arrested, police said.

The victim was attacked after confronting the group over hate speech, Police Chief Marcia Harnden said in a statement.

According to Captain Brad Liles, the investigation is ongoing and police are looking for others who were allegedly involved.
