Celebrity Big Brother: Security called in after Stephen Bear's angry outburst

Stephen Bear has become the second Celebrity Big Brother contestant to be given a formal warning, after security had to be called to the diary room.

Aubrey O'Day was issued with a final warning by Big Brother on Wednesday for spitting in Bear's sandwich, but now the Ex On The Beach star has earned a warning of his own for "unacceptable" behaviour.

Angry after a row with Heavy D in the early hours, he threw a mug against the wall in the smoking area, damaging a mirror.

But when reprimanded by Big Brother in the diary room and told he was being separated into a spare room, he complained "This is a joke!" and tried to leave.

Security entered the diary room to ask Bear to sit down. He then apologised and accepted his warning.

The two had clashed after Bear, who shares a bed with Storage Hunter's Heavy D, brought Chloe Khan into the bedroom.

Khan and Bear had kissed earlier in the programme as part of a game of truth or dare.

However, with most of the housemates in bed, the two kissed again in the bathroom, before moving to the bedroom. Heavy D complained, sparking the argument.
