Vancouver police are investigating an attack on a man who was heading to the vigil held at the Vancouver Art Gallery for the victims of the Orlando nightclub shooting.

Dallas Groot told Global News that he was carrying the Pride flag as he was walking to the vigil on June 12 when a man with a black hoodie attacked him from behind with an unknown weapon. The blow knocked him to the ground. He went to the hospital after the attack, which left him with a bruise.

Meanwhile, the Vancouver Pride Society will be meeting with Vancouver police about security for the parade, which will be held on July 31.

On the same day as the Orlando shooting, Los Angeles police arrested a 20-year-old man who had a cache of weapons, ammunition, and explosive-making materials in his car and who was planning to attend the L.A. Pride Festival.

The suspect has been identified as James Wesley Howell of Indiana.

Police are still trying to determine his intentions. No connection has been made between the Orlando attack and Howell, and police have not established that Howell intended to cause harm at the Pride event.
