FAA officials are investigating a drone that flew over a 4/20 rally at Denver's Civic Center Park Sunday, KMGH-TV reports. Police asked two men to leave the top of a nearby building.

Police did not file an incident report, and could not tell 7NEWS their names, where they were from and if they were working for a production company.

In not exactly surprising news, some members of the crowd noticed the robot whizzing above their heads, the TV station reported.

 

It didn't belong to Denver police, Denver Post City Editor Larry Ryckman reported on Twitter.

Also via Ryckman, here's video of the drone:
