Red Line station Wednesday night when a deputy repeatedly asked if he had a ticket.
The man didn't answer, so the deputy took hold of his hands to stop and question him.
Whitmore says the man broke free, raised clenched fists and charged the deputy several times. He was Tasered, then shocked twice more when he got up and charged again.
Whitmore says a pipe used to smoke drugs fell to the ground during the scuffle.
