District Attorney Tom Hogan says Rambo, 59, misappropriated funds and stole from the township.
According to officials, Rambo, who resides in Coatesville, Pennsylvania, was confronted in the past with prior instances of misappropriating funds and had agreed to repay the township, but then continued to misappropriate funds.
Officials say he approved reimbursement for forged medical bills totaling more than $456.
Chester County detectives will continue to review records and interview witnesses to determine the full extent of the thefts.
