Two people fought each other at MacArthur BART Station Monday, holding up a train during the evening work commute, officials said.

A report of the incident came in about 5:20 p.m., said BART spokesman Taylor Huckaby. Officials initially said someone had been assaulted with a Taser, causing the train to be held up about 18 minutes as police investigated.

After police investigated, they found the Taser report was false and that two people were in an altercation, said BART Lt. Terence McCarty.

Multiple people aboard the train told The Chronicle they saw a Taser was used in the fight.

Neither party opted to press charges, McCarty said.

No further details were immediately available.
