The pills were found Sunday when the cake was served and some of it eaten, The Hartford (Conn.) Courant reported Monday.

Though no one was sickened, clients were examined at a local hospital, the police said.

The staff member who baked the cake told police she accidentally spilled her medication in her kitchen but didn't think any of it had fallen in the cake batter, the Courant reported.

Police did not publicly name the medication or say how many pills were found in the cake. No criminal charges have been filed and the incident remains under investigation, the Courant said.
