A photo of a man riding on a "crotch rocket" motorcycle with an infant lying on the gas tank is making its way around social media. The photo purports that the man was seen on SH 321 in Liberty County on or before the Memorial Day weekend, but so far no one has identified the man to authorities.

With so little information available, said Liberty County Sheriff's Capt. Ken DeFoor, the agency can't even be sure if the photograph was taken in the jurisdiction of the sheriff's office or another law enforcement agency, such as a city, or if the photo was even taken in Liberty County.

"Until it can be determined where the photo was taken, there is really nothing we can do at this point," DeFoor said.

The captain said he is concerned about the child pictured in the Facebook post and hopes more information comes forward to aid in the investigation.

"It appears the motorcyclist was pressing the child between himself and the gas tank to keep it on the bike. That is never a good idea. It's foolish and dangerous," he said.

It's also illegal, according to Sgt. Rob Willoughby, who oversees the Liberty County office of the Texas Department of Public Safety.

Willoughby said he saw the Facebook post as it was being shared by friends and is also concerned about the child's welfare.

"It's very concerning. Here is a guy on a high-powered sports bike and he's carrying a small child. The child can't hold on for himself," Willoughby said. "It's a disaster waiting to happen."

According to Willoughby, the bike appears to be a gray Suzuki Hayabusa.

State law says that a motorcycle operator cannot carry another person under the age of 5, Willoughby said. In order for it to be legal for children 5 and over to ride, the motorcycle must be designed to carry one than one person and be equipped with a permanently mounted seat specifically for a passenger with footrests and handholds.

"My advice for people who see someone illegally riding with a child is to get a license plate of the vehicle and call 911. This is a safety issue," Willoughby said.

Anyone with information about the motorcyclist pictured is asked to call the police department or sheriff's office in their jurisdiction, or call the Liberty County Sheriff's Office at 936-336-4500.
