Man arrested on suspicion of assault after waving knife in road rage video

Long Beach police on Thursday arrested a Long Beach man on suspicion of assault with a deadly weapon after he was shown on video waving a large knife at two men during a road rage incident earlier this week.

The man, 33-year-old Matthew Caple, was released on $30,601 bond Friday morning.

Detectives started investigating the case on Wednesday after the video from a bystander, posted on YouTube, showed a suspect arguing with two men in a silver Jeep. He appears to show the large knife to the men, lick it and point it at them before putting it down.

A victim reported the incident to police shortly after the incident, which took place on Broadway and Alamitos Avenue.

“As soon as he showed the knife and flashed him and waved it at him, that’s considered assault with a deadly weapon,” police spokeswoman Shaunna Dandoy said.

A suspect does not necessarily have to touch a victim to be arrested for assault with a deadly weapon because they have the ability to go further, she said.

Charges will be filed on July 26, when Caple is expected to appear in court, Dandoy said.
