In May, Dwyer pleaded guilty in Anne Arundel District Court to drunken boating and was sentenced to 30 days in jail, a $1,000 fine and a year of supervised probation, but he appealed. In Circuit Court this month, he again pleaded guilty, but his attorney said Dwyer hoped to avoid jail time.

After Dwyer's plea this month, a spokesman for the Howard County state's attorney's office, which prosecuted the case, said the judge plans to examine documentation of Dwyer's alcohol rehabilitation and statements from crash victims. The office declined to comment Tuesday.

Shortly after the boat crash, Dwyer acknowledged that he had been drinking and apologized. Wearing a neck brace and sitting in a wheelchair outside the Maryland Shock Trauma Center in Baltimore, he said, "I deeply regret my actions and ask for your forgiveness."

In January, Dwyer posted a letter to supporters on his Facebook page, saying he had been facing difficult personal and professional challenges and turned to alcohol to cope. He said he voluntarily completed an alcohol intervention program and was committed to counseling and attending Alcoholics Anonymous meetings.

Tuesday's arrest came on the heels of an unrelated incident Sunday in which Dwyer was the victim of an assault by a neighbor, according to another police report. The neighbor was arrested after he ordered his dog to attack Dwyer, the report said.

In June, Dwyer was cited for crabbing on a Wednesday, which is prohibited. Online court records show he paid a $125 fine.

Dwyer was first elected to the House in 2002, representing District 31, which includes Pasadena, Gibson Island, Brooklyn Park and part of Glen Burnie. Dwyer is paid a salary of $43,500 a year as a legislator.

One of the most conservative members of the House, Dwyer has made his mark fighting against same-sex marriage, gun control and benefits for illegal immigrants.

Dwyer briefly considered running for state Senate, but instead said he'll run for delegate in 2014. In July, he held a raffle of AR-15 and AK-47 assault-type rifles to support his campaign.
