Police arrested dozens of people this weekend for alcohol-related offenses, including two assaults on police officers.

The unusually high number of arrests was partly due to police commanders’ efforts to crack down on drunken driving and other moving violations, said Sgt. Trent McKinley, a Lawrence Police Department spokesman.

From Friday to Sunday, 29 people were booked into the Douglas County Jail for DUI or driving with an open container of alcohol. That’s roughly three times the number of similar arrests in a typical weekend, according to the jail logs, though the frequency of these incidents varies.

Some of the incidents were uglier than usual, McKinley said. Two police officers were attacked and injured by suspects while making arrests.

In one incident, a man punched an officer in the face after being stopped while driving from the scene of a fight at Haskell Indian Nations University about 2 a.m. Saturday. He was arrested along with another occupant of the car, who was booked on suspicion of driving with an open container and possession of marijuana and drug paraphernalia, McKinley said.

On Sunday, another officer was injured while trying to remove a person from the Lawrence Community Shelter at the request of staff, who said the man was disorderly and belligerent. After the man kicked responding officers, they used a Taser to arrest him, McKinley said. He was checked at the hospital before being taken to jail.

There were other arrests in Lawrence this weekend as well, and 22 tickets for moving violations. These were among the alcohol-related arrests:

• Three for tampering with ignition interlock devices.

• Three for disorderly conduct.

• Two intoxicated pedestrians.

• Five for leaving the scene of an accident.

• Three for battery.

• Six for open containers.

• Two for criminal damage.
