A shooting occurred early Saturday morning near the prison facility in Texas where Ghislaine Maxwell is being held, sources familiar with the situation told NBC News.

Officers from The Federal Bureau of Prisons heard the gunshots outside of Federal Prison Camp Bryan before responding and engaging with the suspected shooter, the sources said.

The BOP confirmed that an active shooter incident took place near the prison in Bryan, Texas, Saturday at 1:15 a.m.

No guards or staff members were injured, the sources and the BOP said. The shooting appeared to be the result of a block party near the prison where two rivals -- or rival gangs -- took part in a shootout.

The shootout was not directly related to Maxwell's incarceration at the prison, the sources said.

The BOP said in a statement that an active investigation is ongoing.

"We are deeply grateful to our staff and law enforcement partners for the rapid and professional response," the BOP said.

Maxwell's move to Federal Prison Camp Bryan earlier this month was met with backlash from those who said she should not be held at a minimum-security prison considering her sex offense charges.

Shortly after she was transferred, the prison said it was amping up security measures in response to her arrival, a senior law enforcement official told NBC News.
