A former Uber driver faces four years in prison for his role in an interstate gun trafficking ring. Law enforcement officials said the group smuggled dozens of guns into New York City from South Carolina, North Carolina and Tennessee.

As reported by the Daily News, Marlon Manswell, 32, admitted to driving his accomplice from the Port Authority Bus Terminal to Brooklyn to sell guns. Authorities said he pleaded guilty to criminal possession of a weapon in the second degree, criminal sale of a firearm in the second degree and conspiracy in the fourth degree.

Manswell’s four-year prison sentence will be followed by five years of probation. He was fired from Uber in October 2015 after his arrest, according to a company spokeswoman.

The NYPD’s Gang Squad Brooklyn North used undercover surveillance and wiretaps to build the case. Their investigations led to the seizure of around 50 illegal guns including revolvers and semiautomatic weapons. The ring transported them into New York City from out of state via the so-called Iron Pipeline route, where the majority of New York’s illegal firearms come from.

Three others were also arrested and charged for their involvement in the gun trafficking ring. Manswell and his accomplices helped sell the guns to undercover officers from June to October 2015.

New York has some of the nation’s strictest firearms laws. Individuals facing weapons charges in the state should contact the experienced attorneys at Brill Legal Group to fight the accusations.
