"The Bachelorette" star Shawn Evans says he was the victim of "reality-star-on-reality-star crime" ... after getting hit in the head by a brick.
The alleged brick tosser is Mickey Rappaport, aka Mickey Coco, who was featured on MTV Canada's show "Grand Benders."
Shawn was leaving a bar in Grand Bend, Ontario last week when Mickey allegedly hurled a brick from a second story balcony in Shawn's direction, hitting him in the head.
Canadian cops arrested Rappaport for assault with a weapon and busted Rappaport's son Justin as well ... for obstructing a peace officer.
Evans says he suffered a concussion and plans on suing.
