TARZANA, Calif.–Singer Bobby Brown was arrested in Tarzana today on suspicion of driving under the influence of alcohol or drugs, his second such arrest in the San Fernando Valley this year.

Brown was arrested around 1 a.m. after an officer observed his Acura sedan being driven erratically in the area of Ventura Boulevard and Corbin Avenue, according to Sgt. Duane Aikins of the Los Angeles Police Department’s Topanga Station.

He posted $25,000 bail and was released from a Van Nuys jail at 3:55 a.m., police said.

The 43-year-old former spouse of the late pop icon Whitney Houston pleaded no contest in April to a misdemeanor drunken driving charge stemming from a March 26 arrest. He was sentenced to a 90-day alcohol program, three years probation and a $390 fine plus penalty assessments, according to Frank Mateljan of the Los Angeles City Attorney’s Office.

He was arrested about 12:20 p.m. March 26 at Victory Boulevard and Wilbur Avenue. According to the California Highway Patrol, the singer was driving west on Victory just east of Yolanda Avenue in moderate traffic when an officer saw him talking on a cell phone.

“Mr. Brown displayed objective symptoms of intoxication and was asked to submit to a series of field sobriety (tests) that he was unable to perform as explained/demonstrated,” according to a CHP report at the time.

Brown also has a DUI conviction on his record stemming from an arrest in Georgia in 1996. He pleaded guilty and served eight days in jail.

Brown rose to fame with the group New Edition. He was married for nearly 15 years to Houston, who died Feb. 11 at the Beverly Hilton hotel, and is the father of the late singer’s only child, Bobbi Kristina.
