Former India captain Anil Kumble termed the incident involving Australian cricketer Luke Pomersbach as 'unfortunate'.
Pomersbach was arrested for allegedly molesting an American woman and severely beating up her fiance at a city hotel in New Delhi.
"I was on a flight. I just landed and whatever reports I have seen is from the press, media. Luke, so far with the RCB, has been exceptional, but it's an unfortunate incident. It is disappointing," said Kumble, mentor of the IPL team, Royal Challengers Bangalore.
"RCB will certainly not play Luke henceforth and we will co-operate with those who are investigating the incident," he added.
He also promised an internal investigation into the issue.
"Surely, internally also, we will look into this matter, it's a serious matter," he said.
Meanwhile, on Twitter, RCB owner Siddhartha Mallya cast aspersions on the molestation victim's character, tweeting: The girl who is accusing Luke is saying he hit her 'fiance'...what a load of f***ing shit. She was all over me asked for me bbm pin, so if he was her fiance she wasn't exactly behaving like a future wife.
"I woke up this morning with 100+ messages regarding luke... I still don't know what went on....
"The girl who is accusing Luke is saying he hit her 'fiance'... what a load of f***ing shit. She was all over me asked for me bbm pin, so if he was her fiance she wasn't exactly behaving like a future wife. Everyone wants there 15 minuets.
"First SRK, now this... everyone loves a good scandal. Why can't ppl just enjoy the cricket...has everyone forgotten chris' 100 last night?
"If luke is in the wrong, then trust me he will face the necessary sanctions. But what this girl is doing is idiotic."
The RCB cricketer allegedly misbehaved with the woman, a US citizen, at a five-star hotel early this morning and has been arrested, the police said.
The victim claimed that the player invited himself for some drinks with the couple and some common friends from Mumbai in their room. She left the men alone and went to her bedroom for catching some sleep but Luke followed her and misbehaved with her.
When her fiancee intervened, Luke allegedly beat him up, she alleged.
The woman's fiancee has been admitted to a hospital where a CT scan has been done, doctors attending to him said.
Pomersbach has not played a single IPL match so far this season.
The 27-year-old Pomersbach's conduct prompted RCB owner Vijay Mallya to suspend the batsman till the time he is cleared of the charges.
