The Monterey Park gunman was banned from the dance studio where he massacred 11, it is claimed.
Huu Can Tran, 72, was kicked out off Star Ballroom Studio and Lai Lai club around five years ago for being "too argumentative" and "pestering" women, according to members of the clubs.
Tran fired 42 rounds in the Star Ballroom Studio on Saturday night in California, US, killing 11 and wounding 9 during the Lunar New Year massacre.
