The man accused of stabbing three people at a downtown Davenport bar Saturday was pinned to the ground and disarmed by bouncers as police were called, the bar owner said Monday.

Don Davison, owner of Shenanigan's, said he saw a commotion near the restrooms and hailed security to break it up. In addition to himself and a bar manager, Davison said, there were six security guards working Saturday.

“It is a fluke thing,” he said. “It was St. Patty’s Day, and there were thousands of people down here.”

Long restroom lines sparked the incident, he said, adding that suspect David Ramm started shoving people before pulling out his knife. Providing security in the restroom areas is a challenge, he said, because of the need for customer privacy.

“I’ve been in the bar business over 20 years and never had anything like this happen,” Davison said. “It disgusts me.”

Ramm, 35, of 9920 123rd St., Davenport, faces three felony counts of willful injury causing bodily injury and one count of going armed with intent. The incident occurred just after 4 p.m. Saturday. Ramm spent about five hours in jail before he was released from the Scott County Jail on $5,000 bond.

The three stabbing victims have not yet been identified. Although police spoke with them at the scene, Davenport Police Maj. Don Schaefer said Monday, the victims have not been "formally" interviewed.

Police did confirm one of the victims was a friend of Ramm's who was stabbed when he tried to intervene. Two of the victims were hospitalized for observation, police said, and one underwent surgery.

Davison took over ownership of Shenanigan's in October, and police said they have responded to 24 calls for service since it reopened. A majority of the calls, 16, were for disturbances.

In 2010, the former owner of Shenanigan's was among five downtown tavern owners to pool their money to pay for extra police patrols in the area. The private funding came in response to complaints to aldermen that police were taking up to two hours to respond to routine calls outside of downtown.
