A former top White House aide was arrested on Thursday in the Maryland suburbs on charges that he stole merchandise from a number of retailers, the police in Montgomery County, Md., said Friday.

The former aide, Claude A. Allen, 45, was President Bush's top domestic policy adviser until resigning last month. Known as a rising conservative star, he previously served as deputy secretary of the Health and Human Services Department, and in 2003 the White House announced its intention to nominate him to a seat on the federal appeals court based in Richmond, Va. Democrats raised questions about the nomination, and it never came to a vote.

The police said Mr. Allen was seen on Jan. 2 leaving a department store in Gaithersburg, Md., with merchandise for which he had not paid. He was apprehended by a store employee and issued a misdemeanor citation for theft, said Lt. Eric Burnett, a spokesman for the Montgomery County Police Department.

A statement issued on Friday by the police said store employees saw Mr. Allen fill a shopping bag with merchandise and put additional items into a shopping cart. He then sought, and received, a refund for some of the items and left the store without paying for others.

The Police Department said that as a result of an investigation it opened after the initial incident in January, it found that Mr. Allen had received refunds of more than $5,000 last year at stores like Target and Hecht's. Mr. Allen was arrested on Thursday and charged in connection with a series of allegedly fraudulent returns. The police said he was charged with a theft scheme over $500 and theft over $500.

"He would buy items, take them out to his car and return to the store with the receipt," the police said in the statement. "He would select the same items he had just purchased and then return them for a refund."

…Mr. Allen went to the White House after his nomination to the United States Court of Appeals for the Fourth Circuit stalled in the Senate. The nomination never came to a vote, in part because some Democrats raised questions about comments he had made in 1984, while working for Senator Jesse Helms, Republican of North Carolina. He had been quoted as saying that Mr. Helms's opponent that year was vulnerable because his campaign could be "linked with the queers."
