Narrative:

Assigned to park at a gate; we crossed runway 27 and the captain continued to taxi right of an aircraft parked in a gate there. I told him to come left and then said come left loudly. The jumpseater yelled stop! I quickly stopped the aircraft using the brakes. I talked to the captain about this event on the phone this morning. He said that he may have been tired. I decided it was best to issue a report; and told him that I was going to. He said they would as well.
