Raymond Lam reportedly snatched a mobile phone away from a fan, telling his staff to check the pictures taken.
According to a report on Oriental Daily, Raymond was in Hengdian shooting for TV series Detective and Doctors when he discovered fans were taking pictures of him.
He appeared unhappy about it, just before he took the fan's phone away.
Photos taken at the scene prove that Karena was also present at the shoot, and it is believed that he probably feared the exposure of his girlfriend visiting him on the set.
Netizens expressed their disappointment in their idol over his aggressive behaviour on Weibo, but there were also 'Fung Mai' (hardcore Raymond fans) defending him, saying that Raymond wanted to prevent reporters from taking photos in secret, so he snatched the phone away.
Reporters tried to contact Raymond and Karena to comment, but unfortunately they did not respond.
A few days prior to the incident, Raymond had also been spotted "body guarding" his girlfriend on the streets.
