CRYSTAL BEACH, Texas – There were 400 calls for service on the Bolivar Peninsula during the 'Go Topless' Jeep Weekend at Crystal Beach, according to Henry Trochesset, Galveston County sheriff.

From Friday to Saturday, there were 68 arrests -- 30 of which were alcohol-related and 10 of which were DWI-related -- 10 major auto-pedestrian accidents, eight major car crashes and 14 minor accidents, Galveston County Sheriff Henry Trochesset said. Those numbers don't include Sunday.

He said at one point, LifeFlight was being treated as a regular ambulance since no emergency vehicles were left on the island to respond to calls.

“It was just too many people, it was overwhelming,” Jacob Taylor said.

Taylor was one of the thousands who showed up for the Go Topless Jeep event in Galveston County, but it wasn't what he expected.

“When you get so many people in a certain area, you gonna have problems,” he said.

Kyle Nelson said he and his friends left when they heard gunshots.

“It was pretty chaotic. It got pretty bad,” Nelson said.
