The Metropolitan Police Department arrested an 81-year-old man in Northwest D.C., accusing him of assaulting a street vendor with a machete.

Police said that at 5:19 p.m. Tuesday, they found the adult male victim in the 3100 block of 14th Street NW suffering from laceration wounds. 

An investigation found Julian Bueno got into an argument with the unnamed vendor over returning a product and that the octogenarian swung the big knife at the vendor.

Police found Mr. Bueno near the scene and arrested him. The suspect, of no fixed address, faces charges of assault with a dangerous weapon. 

The victim refused transportation to a medical facility by D.C. Fire and EMS, police said.
