Video: Student says LAPD officer pulled her off Metro train, arrested her for having her foot on seat

LOS ANGELES -- (KTLA) -- A use-of-force investigation is underway after an 18-year-old woman was pulled off a Metro train and arrested Monday afternoon by an LAPD officer who she said confronted her for having her foot on a train seat.

The incident was captured on a cellphone video that was shared to Facebook, earning nearly 1 million views by midday Tuesday. Brock Bryan, who recorded the 10 1/2-minute video, can be heard objecting to the teen's treatment by the officer, alongside other witnesses.

One of those witnesses was also arrested after allegedly spitting at an officer.

Bethany Renee Nava of North Hollywood was riding the train when police say she was being loud and boisterous, prompting her to be removed and arrested, Los Angeles Police Department Officer Mike Lopez said.

In the video, Nava and other witnesses repeatedly say that the girl had only had her foot on a seat in the train when the officer confronted her. Bryan said the teen was on a Red Line train when the arrest took place at the Westlake/MacArthur Park station about 3 p.m. Monday.
