D.C. police arrested 11 people outside Nationals Park on Thursday in an effort to stop ticket scalpers, officials said.

Several of those who were arrested said they were merely fans or season ticket holders who never took cash or exchanged a ticket.

Gwen Crump, a police spokeswoman, said officers were “working in conjunction with . . . Major League Baseball to address illegal ticket sales.” She said that police witnessed scalping before Wednesday’s game, so extra officers were deployed Thursday.

Season ticket holder Patrick Coneely, 46, said he was arrested after he stood near the ticket window, raised a ticket in his hand and leaned over to talk to a stranger. “They just put the cuffs on me and said I was ticket scalping,” he said. “I never asked for any money.

“This is how a season ticket holder gets treated,” said Coneely, who was fined $50.
