A Labour MP has been forced to close and move her parliamentary office.
Shrewsbury MP Julia Buckley said her office in Wyle Cop had been attacked three times in three weeks.
A 53-year-old man was arrested last month on suspicion of criminal damage.
West Mercia Police confirmed the male has since been released pending further inquiries.
Buckley became Shrewsbury's first female MP during last year's general election.
