A firefighter who “mooned” a San Antonio Police Department Eagle helicopter earlier this year has been suspended 20 days, city discipline records show.

Engineer Carthel Williams was originally given an indefinite suspension in early November, but the punishment was later shortened as part of a signed release and settlement agreement with San Antonio Fire Department Chief Charles Hood, KSAT reports.

The incident took place April 29 while Williams was on-duty and in full uniform. Pictures were taken and later distributed to other people, suspension records show.
