A Boyds man was arrested Thursday after allegedly stabbing three people in Gaithersburg the night before, according to police.

At approximately 9:45 p.m. Wednesday, Gaithersburg police responded to the 700 block of Quince Orchard Road for a report of a stabbing. Three males were found with lacerations and were taken to a local hospital with critical but non-life-threatening injuries, according to police.

Jose Leandro Castillo, 34, was arrested in relation to the stabbings and charged with first-degree assault, second-degree assault and reckless endangerment, the Gaithersburg Police Department wrote in a statement. He is being held without bond.

Charging documents say Castillo got into an argument with the victims after he “thought he heard them say something sexual” to his girlfriend.

The girlfriend said the three males assaulted Castillo, and he responded by pulling out a knife. He then “began to stab them all,” charging documents say.

He then fled the scene. He was arrested Thursday, according to police.
