An argument over a bus rider's dog escalated into a bloody fight aboard a Bronx bus on Monday afternoon. The victim, who required 12 stitches for lacerations on her face, told reporters, "She slashed my face because I went to go touch her service dog."

Police say the incident took place around 2:13 p.m. on a westbound BX2 bus, when a 22-year-old woman apparently reached over to pet another woman's dog. The dog owner allegedly objected, the pair argued, and the dispute turned physical. According to the NYPD, the dog owner slashed the 22-year-old as well as her 20-year-old female friend during the fight.

After being slashed, the two women left the bus at East 149 Street and Morris Avenue and ran to Lincoln Medical Center for medical attention. The dog owner also got out at that location; police say she left the scene in a green SUV taxi, headed westbound on East 149th Street.

The 22-year-old victim explained to WCBS 2, "When I went to go touch [the dog] she got mad, so we ended up having a conflict going back and forth arguing," and admitted her temper got the better of her, "I went to go leave the bus and then she just did something that got me aggravated so I went back to her and once I grabbed her by her coat, she went to go hit me, when I hit her."

"I don’t know, we ended up going to the floor and everything went black from there… got my face sliced and that was it," she said.

In another interview, she added, "I never knew it was a service animal."

Police released security camera video of the suspect leaving in the green taxi and described her as being about 30-35 years old and 5'7"-5'9" tall, with eyeglasses. She was last seen wearing a dark colored baseball cap, a black waist-length coat, black pants, black and white sneakers and carrying a black shoulder purse and a small white dog.
