Maryland State Police are on the scene investigating a crash that blocked all northbound lanes on I-95 near Joppa Monday morning.

A juvenile passenger was transported to Johns Hopkins Hospital by way of helicopter, according to police.

All northbound lanes were still blocked off as of 1 p.m., with a detour via The Maryland House underway. Police ask that residents avoid this area, if possible.

When crews called for the medevac helicopter, a drone was flying nearby that created a serious safety risk, according to Harford County Fire and EMS. This prompted the agency to remind residents, on social media, about their drone use around emergency scenes, especially while helicopters are in use.

“The flying of drones over or near an active emergency scene is prohibited by FAA rules,” the post said. “Please do not hinder our operations by flying a drone irresponsibly.”
