Timonium, was charged with disorderly conduct and related charges; Benjamin Aduna, 21, of Baltimore was charged with resisting arrest and related charges. Two others were charged on criminal citations for disorderly conduct and failure to obey a lawful order.
Police had said the theater overbooked the show, but Recher disputed that. People paid at the door, he said, and the venue closed its doors when it had reached its capacity of 630 people.
"We've done everything aboveboard," he said.
Recher said he thinks some people publicized the show through social media and "word of mouth."
"It blew up, and a million people showed up," he said.
There were no incidents inside the theater Saturday, Recher said, adding that it hosted several events that day. "Everybody was having fun inside," he said.
Local Goodwill officials said they were not aware of the Theta Mu Mu event and no one had coordinated with them for a clothing drive at the theater.
Although Towson University celebrated homecoming over the weekend, Gay Pinder, a university spokeswoman, said the problems in town did not have anything to do with the school. She said none of the people arrested were Towson students.
She added that the university "has consistently partnered with the Towson community to ensure our students' safety in and outside of the campus boundaries. We're always concerned with the safety of our students."
Nancy Hafford, executive director of the Towson Chamber of Commerce, called the violence "an isolated event."
In August, the chamber took part in a forum with police, Towson bar owners and local college administrators to discuss issues such as crowd control and underage drinking, she said.
"Our Police Department has made some really great changes where they've moved some police officers to later in the evening when bars are closing and there's more activity," she said. "And we really have not had many problems until, unfortunately, Saturday night."
The Towson precinct commander, Capt. Jonathan Trentzsch, told the Towson Times after the August meeting that the department's concerns were underage drinking and crowds. "We're trying to get a handle on that," he told the newspaper.
Trentzsch was not available for comment Monday.
