Bryan Christopher Hall pleaded guilty to robbery and aggravated assault in Lycoming County Court Friday.

The charges against Hall, 28, of Hughesville, were the result of two separate cases last year.

Hall was incarcerated in October after admitting to police he held up the Uni-Mart on North Main Street in Hughesville days earlier.

Hall reportedly walked into the store wearing a ski mask and armed with a knife.

An anonymous tip helped lead borough police to his arrest, according to reports.

The following month he was charged with assaulting a correctional officer.

Hall, an admitted heroin addict, told Lycoming County Judge Marc F. Lovecchio that has been using drugs for a number of years.

His sentencing is set for 10 a.m., May 6.
