HOUSTON – A man accused of robbing a Jimmy John's in Midtown injured an employee and shot an innocent bystander Monday morning while running across a parking lot, according to the Houston Police Department.

Police said an employee was opening the Jimmy John's at 2404 Bagby St. when an armed man attempted to rob the restaurant. The man pistol-whipped the employee before running off empty handed, investigators said.

While running away from the sandwich shop, investigators said the man also shot a person walking across the parking lot in the head. The victim walked to a nearby Walgreens and collapsed, police said.

HPD officials said the victim was awake and conscious when paramedics took him to the hospital.

Officers said detectives are interrogating a suspect, but it's still unclear whether this person is the gunmen.
