HOUSTON -

Four women, including a 15-year-old, suspected to be pregnant, got into a wild brawl on a METRO bus.  Two girls were knocked down and punched in the face repeatedly.

Once the bus driver realized the girls were fighting, he said he pulled over at Gessner Road and Braeswood Boulevard in southwest Houston.

A witness who recorded a video of the fight on her cell phone said the most disturbing part was when one of the girls yelled out that she was pregnant and wanted to fight.

"The three girls that I think were related started to jump on the one girl," said the witness, who asked to remain anonymous.  "One of those three girls said she was pregnant.  She was shouting that she was 15 and would fight."

Tom Lambert, interim METRO President and former METRO Police Chief said three people, including the 15-year-old and her 42-year-old mother, received citations for fighting in public.  Lambert did not confirm whether the teen was pregnant, but he said no ambulance was called to the scene.

"Are we going to have instances that occur?" asked Lambert.  "Yes, we are.  We are prepared to respond to those.  If you look at the total number of buses, the service area, and how many people we carry on a daily basis, we think we have a safe system."

Lambert reiterated that the bus driver responded appropriately.  He said the driver pulled over to a safe location, allowed people to leave, and called dispatch.

Lambert said METRO police showed up within 7 minutes. 

No one was arrested, and none of the women wanted to file assault charges.  However, police and the Harris County District Attorney said they would evaluate the witness' cell phone video to decide whether charges should be filed.

In the past 13 months, METRO said the fight was the only one reported on that particular route.
