Long Beach Police Chief Robert Luna was hit by a truck and knocked into lanes of traffic on Friday while walking around El Dorado Nature Center, police said Saturday in a message on Twitter.

The message from the department said the chief was able to call for medical aid and was transported to a local hospital for treatment.

A police spokeswoman said the collision happened at 3:45 p.m. Friday in a crosswalk on E. Spring Street.

Luna was off-duty at the time, said Arantxa Chavarria, spokeswoman for the department.

“He suffered minor injuries and is at home recuperating,” she said.

Police said the truck drove into the crosswalk, and the driver of the truck stayed at the scene and is cooperating with the investigation.

In a statement, Luna thanked “everyone for their well wishes, and I am thankful for the support I am receiving while I recuperate.”

The chief is “in constant contact with the Assistant Chief of Police and will remain engaged in department operations while receiving follow up care,” the statement said.

Luna, who began as a reserve officer with the LBPD in 1985, has served as chief since 2014.
