A resident of the Alamo Ranch Apartment Homes reported a suspicious package Friday that turned out to only be heavy whipping cream.
The resident received the package in his mailbox, opened it and found a suspicious vial inside.
He took it to the leasing office and workers there contacted the authorities.
Bexar County Sheriff's Office deputies arrived at the scene in the 11000 block of Alamo Ranch Parkway around 4 p.m. Friday.
They followed standard protocol and called in representatives from the Fire Marshal's Office and Emergency Management to investigate.
The complex was not evacuated.
