A mob of May Day protesters chased down a man waving an American flag in Cuba on Monday.

Video from the incident shows a man carrying the flag over his head and sprinting out in front of a huge crowd on people marching with a banner.

After ducking under the banner, the man ran down the empty street, only to be chased by parade personnel.

About 20 people captured him and ripped the flag away. He struggled with security personnel before five people then hauled him away.

The man's fate is unknown.

Reports indicate Cuban dictator Raul Castro was in the crowd and watching the man's protest.
