A Citizens Bank branch in Squirrel Hill was robbed Saturday for the second time in nine days.
The incident marks at least the fourth time since Halloween that a bank branch in that neighborhood has been robbed.
Police have not discussed details of Saturday's robbery, which took place in the 1800 block of Murray Avenue, other than saying no arrests were made.
A sign on the door of the bank building after the robbery said the bank was closed because "We are experiencing technical difficulties."
Police are also still searching for the person who robbed the Citizens branch on Nov. 9, described as a 5-foot-8 white man who put a note on the counter and demanded money.
