An attempted break-in was committed at jewellers Goldsmiths of Shrewsbury, the second in a month after £20,000 of watches were stolen in April. Pomona Grocery in Castle Gates was also broken into.
Shrewsbury police inspector Saf Ali explained that extra security measures in place at the jewellers meant the break-in attempt was called in quickly, and wanted to reassure the public.
"Because of what we had in place, it was called in quickly," he said.
Helen Ball, clerk of Shrewsbury Town Council, said: "We are thankful to West Mercia Police for increasing patrols in the town centre at such a challenging time and these patrols have proved successful in the apprehension of this individual.
"The message is clear from all partners operating in Shrewsbury town centre, we will do everything to ensure that businesses can trade safely, that these unwelcome activities are stamped out and the public are happy in knowing Shrewsbury is a lovely place to visit and shop."
Earlier this week, money was stolen and a door was smashed in a break-in at Darwin's Sandwich Evolution in Shoplatch.
Inspector Ali said that officers are looking for one other person in connection with town centre burglaries.
Two arrests were made following those incidents, and police made the issue a priority and increased patrols.
