A Delta Air Lines employee remains in the hospital, and a suspect is in custody, after a vehicle-pedestrian accident last week at Detroit Metropolitan Airport. 

While authorities are providing few details, they did confirm that the employee was struck by a catering truck. 

"Our hearts are with our colleague who was involved in an accident with a catering truck in Detroit. Nothing is more important than the safety of our people and customers and we will fully investigate what happened," read a statement from a Delta spokesperson on the circumstances. 

The Wayne County Airport Authority Police and Fire crews responded to the Wednesday morning accident on the airfield, and a WCAA spokesperson said one person has been taken into custody. 

The investigation is continuing, the WCAA said.
