The Recher Theatre in Towson could face a liquor board hearing on its weekend event that drew an unruly crowd of 2,500 people, Baltimore County Executive Kevin Kamenetz said today.

County police believe the theater subcontracted out promotion and management of the event to a third party, he said during a news conference this morning.

“And I’ve got a real problem with someone who does that,” Kamenetz said, adding that Police Chief James W. Johnson would forward information to the county liquor board if he deems it appropriate. Liquor license holders “can’t just assume that their responsibility ends at their doorway,” Kamenetz said.

Police used K9 teams to respond to the crowds that jammed York Road and other streets early Sunday, and arrested seven people, including three men who were charged with assaulting police officers. One man was shot, police said, but no one has been arrested in that incident.

Theater owner Brian Recher declined to comment today. He has previously said the establishment closed its doors when the event sponsored by the Theta Mu Mu fraternity, a Baltimore County chapter of the Omega Psi Phi fraternity, reached the theater’s capacity of 630 people. He has also said that no incidents occurred inside the building.

Johnson, who also attended the news conference, declined to name the promoter, but said the event was advertised on social media, which was “instrumental” in drawing such a large crowd.

Police said Monday that the melee erupted early Sunday after a fraternal organization rented the Recher Theatre for a charitable event and an overflow crowd forced the theater to close its doors, leaving hundreds of people outside. Seven people were arrested, but the shooting suspect was still being sought.

Recher said the event featured a DJ, and patrons brought clothing to be donated to Goodwill, he said.

This was the third event the theater had done with Theta Mu Mu members in the past few years, Recher said. "They're very professional, great guys, and they just don't know how it blew up," he said.

The violence came just a month after police officials met with business and officials from Towson University and Goucher College to discuss crowd control in York Road bars and restaurants, where students often congregate and where underage drinking has been a concern.

County Councilman David Marks, a Perry Hall Republican whose district includes Towson, said he wants to work with business owners to explore the possibility of a downtown improvement association that could hire extra security. "It doesn't hurt to have an extra set of eyes and ears," he said.

But Marks and other local officials characterized the crowd problem early Sunday as an isolated incident.

Marks said he was frustrated because the county and the Towson Chamber of Commerce have worked to encourage people to visit downtown Towson. For instance, a block-party series called Feet on the Street has drawn people downtown on Friday nights, and the Towson City Center, a redeveloped office building, recently opened, he said.

"I don't want people to be discouraged from patronizing our businesses," Marks said. "You have all these good things occurring ... and I don't want one bad incident to blunt the momentum we see in Towson."

Police Chief James W. Johnson plans to meet with the owner of the Recher Theatre, other business owners, the county liquor board and the local Chamber of Commerce, police said.

According to its website, the Theta Mu Mu chapter was founded in Baltimore County in 2008. The organization takes part in community service activities such as food drives, reading programs and helping displaced families and single parents. The organization is a "grad chapter" for people who are out of college.

Theta Mu Mu chapter leader Jeff Givens referred questions to Christopher Cooper, the international organization's general counsel. Cooper said he was still gathering information about the incident and did not have enough details to comment on it.

Police said they were inundated by calls after an estimated 2,500 people gathered early Sunday along Shealy Avenue near the theater.

Shortly after the crowds dispersed, a 20-year-old man told police he had been shot and was taken to a local hospital. Police said he was not a college student but went to Towson to go to an event at the theater. He was not identified.
