Member of Arundel exec security detail testifies

An Anne Arundel County police officer who serves on County Executive John R. Leopold’s security detail testified Tuesday before a grand jury, the officer’s lawyer said, as the Maryland state prosecutor’s investigation into Leopold continues.

Officer Mark Walker, a full-time member of the five-person detail, was subpoenaed to appear in the county courthouse on Church Circle, his attorney, Anton L. Iamele, confirmed as the two men left the grand jury room in State’s Attorney Frank Weathersbee’s offices around 2 p.m.

Walker was among three of the officers subpoenaed for an appearance in March, but he did not testify that day, Iamele said. Walker had no comment.

Investigators are looking into whether Leopold used county police officers on his security detail to do campaign work. The president of the county firefighters union has said a member of Leopold’s detail picked up a $4,000 check from the firefighters’ political action committee, an incident that he said investigators asked him about.
