A massive Halloween house party that was allegedly illegally selling alcohol in an empty home in a tony Sandy Springs neighborhood not only brought hundreds of revelers, but also the police.

According to police reports, Sandy Springs Police responded to calls about a party on Powers Ferry Road. When they arrived, they found cars backed up through the neighborhood.

When officers finally reached the home, they found it to be well beyond capacity, and 500 additional attendees were waiting in a nearby Publix parking lot. The police then announced the party was being shut down.

Party organizer Anthony Epps reportedly told police that he owned a property management business that was in charge of the home, and that they had used a promotional company to promote the party being held at the home.

Epps had hired off-duty police to act as security at the party, including his brother Brian Epps, a Rockdale County Sheriff’s Deputy and Chief Tony Scepio of the Clarkston Police Department, who later claimed he was picking up his niece.

Once the house was emptied, Anthony Epps was arrested for Disorderly House and taken to the Doraville Jail.

Deputy Brian Epps has been placed on administrative leave with pay while an internal investigation is being conducted in the Rockdale County Sheriff’s Office.
