LOWELL — A 33-year-old Tewksbury woman is accused of trying to pick up her niece from cheerleading practice while drunk, and then repeatedly fleeing from police who attempted to pull her over, according to police reports.

Andrea Rego, of 29 Ellington Road, was arrested on Oct. 11 following a police pursuit in which she alleged stopped her vehicle twice for police, only to accelerate away as soon as a police officer got out of his cruiser to approach.

Officers began seeking Rego when they got a call reporting a drunk woman was trying to pick up her niece from cheerleading practice at the Snack Shack off Livingston Street, according to a police report.

When an officer arrived at the scene, a witness told police the child’s mother was en route to pick her up, and that the intoxicated aunt was leaving the area in a Chevrolet Trailblazer that she pointed out, according to a police report.

Officer Christopher Lefebvre pulled the Trailblazer over on Livingston Street, but the vehicle accelerated away once Lefebvre got out of his cruiser, according to a police report.

The Trailblazer pulled over again in the area of Corinne Way, but when Lefebvre got out of his cruiser the Trailblazer once again sped away, leading Lefebvre on a pursuit down Livingston Street, to East Street, to Jills Way, where police blocked the vehicle’s path of escape, according to a police report.

Rego smelled of alcohol and was unsteady on her feet as she was arrested, according to a police report. Police found an open bottle of Caldwells Vodka in the Trailblazer, according to a police report.

Once at the police station, Lefebvre attempted to give Rego a field sobriety test, demonstrating a part of the test known as the “one leg stand.”

Rego agreed to take the test, but instead of performing the one leg stand an officer demonstrated for her, Rego attempted part of a field sobriety test known as the “nine step walk and turn,” even though Lefebvre hadn’t asked her to or explained how that part of the test worked.

Rego then refused to continue attempting to perform the test, and also refused a Breathalyzer, according to a police report.

Rego initially faced a second-offense drunken driving charge, but police later learned she was previously convicted of two drunken driving offenses, and submitted a new criminal complaint charging her with operating under the influence of liquor (third offense), according to police reports.

She is additionally charged with open container of alcohol in a motor vehicle, negligent operation of a motor vehicle, failure to stop for police, operating with a suspended license, and marked lanes violation, according to court records.

Judge John Coffey released Rego on personal recognizance at her arraignment on the updated complaint Wednesday in Lowell District Court, and ordered her to consume no drugs or alcohol and to submit to random screens while the case is pending, according to court records.

Rego nonetheless remains behind bars, because she is currently serving a sentence at MCI Framingham in connection with an unrelated case. The details of that case were not immediately available.

Rego’s attorney, Greg Oberhauser, declined to comment.
