Giovanni Gaines, 23, was arrested last week for his alleged involvement in the blast, which injured 10 Oakland police officers during a July 23 march honoring Nia Wilson, Lt. James Beere said Thursday, according to the SF Gate. Wilson had been fatally stabbed at a BART station a day earlier in what initially appeared to be a racially motivated attack, though, it later emerged the suspect had mental health issues.
Police moved in to break up the rally after a group of marchers attacked a man they allegedly thought was a white nationalist, Beere said. As officers tried to de-escalate the situation, an IED suddenly flew their way. The resulting explosion injured 10 officers, including Beere, according to the SF Gate.
Gaines was arrested and booked into the Santa Rita Jail on suspicion of possessing a destructive device, a destructive device near a populated location, use of a bomb to destroy property and exploding bomb causing bodily injury, SF Gate reported, citing jail records.
