At a press conference on Friday, SEPTA Police Chief Thomas Nestel took full responsibility for the way a transit officer handled a fare evasion incident involving a father and his young daughter.

The original video of the incident, which went viral on Friday morning, showed multiple officers trying to arrest Ellis Smith, 20, with his 2-year-old daughter still in his arms. Smith had reportedly did not pay his own fare at the Margaret-Orthodox station on the Market-Frankford line. SEPTA has not released the name of the officer who approached him on the train, but said that he is a 16-year veteran with no prior complaints.

After a verbal altercation between Smith and the officer, the situation escalated quickly.

SEPTA treats fare evasion as a ticketable crime. Last year, the transit police issued 5,100 citations for similar incidents.

This situation, however, raised questions about the length's SEPTA is willing over a $2.25 ride. Nestel apologized, and called it a training error.

If the approaching officer — a 16-year veteran with no prior complaints — didn’t feel comfortable walking away from the situation, Nestel said SEPTA and the Philadelphia Police Department haven’t provided proper training.
