A drone scouring over Pennsylvania State Correctional Institute Phoenix in search of inmate Bill Cosby reportedly led to a lockdown at the prison last week.

Sources told TMZ that the drone zeroed in on Cosby, 81, while he was escorted around the prison yard. The tabloid noted that Cosby uses an escort as he’s legally blind.

Andrew Wyatt, Cosby’s spokesperson who also represented him during his criminal trial, confirmed to USA Today that the drone was spotted over the prison last week. While it’s unclear who was operating the drone, Wyatt said he suspects it was a media drone, as he previously complained about them flying over the comedian’s home in Montgomery County.

Meanwhile, Pennsylvania Department of Corrections press secretary declined to comment on the incident, citing security concerns.

“That said, the agency has installed drone detection systems as part of enhanced security measures at its prisons,” Amy Worden said in an email to the magazine. “Flying drones over prisons in Pennsylvania is against the law and the agency will work with law enforcement to prosecute perpetrators to the fullest extent of the law.”

Cosby has been locked up at the correctional facility since September, when he was sentenced to three to 10 years for sexual assault. Reports indicated that the 81-year-old is angling to appeal his conviction.

Sources told TMZ that Cosby’s attorneys were notified of the incident. It’s not immediately known whether the drone took any pictures of Cosby before the alleged lockdown.
