Shaker Heights Police received reports of thefts from employee cubicles earlier this month at the University Hospitals Management Services Center on Warresnville Center Road.
Lt. Jeff DeMuth said the received two reports on July 10 involving four employees who said their wallets and purses had been either stolen or searched through.
One worker reported stolen credit cards from her purse between 10 a.m. and 4 p.m. Three other employees filed a report that day stating that someone had gone into their work spaces to steal wallets and credit cards.
"Someone's roaming throughout that building," DeMuth said. "They could be working there. We've had other reports of it recently."
