A pair of adult probation officers got quite a surprise when one of their clients showed up at their office in the Berks County Courthouse.

Enrique Ayala was found to have 40 packets of heroin, stamped in red with the words, "GOOD WORK," in his coat pocket during a routine pat-down by the probation officers inside the office Monday afternoon, police said.

Ayala also had $220 in cash, according to court documents. He was charged with possession of heroin.
