A 19-year-old man was busted trying to flee to Mexico to outrun a Manhattan murder charge, authorities said Tuesday.

Luis Gustavo Sanchez Arenales was arrested by US Customs and Border Protection officers around 5 p.m. Saturday at Washington Dulles International Airport with a Mexico-bound ticket in hand, according to federal authorities.

Sanchez Arenales was wanted by the NYPD in connection to the death of an innocent bystander in a Feb. 12 shooting in front of 228 E. 116th St. in Manhattan.

Purcell Gowie, a social worker in East Harlem, was shot in the chest and died at Harlem Hospital.

“This arrest illustrates the seamless collaboration between federal, state and local law enforcement as we captured a fleeing murder suspect and will bring him before a court of law to stand before his charges,” said Anne Maricich, CBP’s acting director of field operations.
