MANCHESTER - Bonnaroo officials are warning festival attendees to better secure their belongings after a man was arrested Friday night in connection with a slew of cell phone thefts on festival grounds.

Buford Munley, 27, of Palmer, Tenn., is charged with misdemeanor theft of property under $1,000, Coffee County Sheriff's Office Capt. Billy Butler said.

Bonnaroo security said they received multiple reports of cell phones and other personal items being pick pocketed during the night's entertainment line up.

Security spotted the activity and officials made an arrest.

In all, 30 items were taken, security reported.

Candice Headrick DeBord posted on Facebook that the thefts took place during the Childish Gambino show at the What Stage.

She said her husband's phone was among those stolen.

Many of the stolen items were recovered, security reported. Attendees still missing phones or other personal items should check with lost and found, they said.

Bonnaroo organizers are reminding patrons to do the following:

Lock valuables in the car or in a Bonnaroo Storage Locker.

Be aware of surroundings. Know where you’re going and who’s around you.

Practice a “neighborhood watch.” If you see something, say something

In addition to Childish Gambino, this year's four-day festival is headlined by Phish and Post Malone.

Bonnaroo organizers confirmed the festival sold out Wednesday night.
