76 Station Robbed at Gun Point

A man with a black semi automatic handgun robbed the 76 gas station on Ardenwood around 9 o'clock this evening.  He was last seen heading west from the station on foot with cash from the till.  A few minutes later a large fight broke out at the Jack in the Box next door.  The fight seems unrelated to the robbery.  Four to five people were fighting each other in "mutual combat".
