Stuart Bingham pointed at a spectator after missing the chance to scoop a huge cash bonus at the UK Championship.
The 2015 world champion faced Zhang Anda in round two at the York Barbican on Thursday.

Bingham was in control of their clash, leading 3-1 as he put together a century break in the fifth frame.
However, the 48-year-old missed the chance to complete a maximum 147 break.
After clearing all but one red, Bingham lined up the black to add to his 105 score.
The world number 25 clipped the pocket, though, to the surprise of the crowd.
Ball-run was not happy either as he reacted by pointing his cue at an audience member.
His response even shocked the commentators, with one commenting: “Someone put him off I think.
“I saw him giving an accusing look at somebody.”
Meanwhile, the other added: “He’s not happy is he. He is not happy. In fact, that’s putting it lightly.”
The incident followed another bizarre moment for Bingham against Mark Williams in round one.
Bingham remarkably potted the black directly from his break-off shot at the start of the tenth frame.

Despite scuppering his hopes of a 147 against Zhang, the Englishman had done enough to clinch the frame before adding another to lead 5-1 in the race to six.
Zhang then pulled off a stunning comeback by winning the next five frames to triumph 6-5.
The Chinese cueist will now face world number one Judd Trump in the quarter-finals on Friday.
His turnaround against Bingham followed a 147 of his own in the opening round.
Zhang secured a maximum break against Lei Peifan earlier this week to guarantee a share of the highest break bonus.
He will split £15,000 with any other players who can match his feat during the remainder of the tournament.
