Arbaaz Khan's cricket betting scandal shocked Salman Khan and family.

There is a blanket of silence fallen over
Salman's familial residence Galaxy
Apartment after Salman's brother Arbaaz
Khan's alleged confession of involvement in
betting for the IPL. While no one in the
family is willing to make a statement, not
even the usually outspoken and forthright
Khan patriarch Salim Khan, a close friend of
Salman Khan says the family is in a state of
shock'.
"I don't think anyone in the family knew
about this (Arbaaz's IPL betting). Arbaaz
didn't share this with anyone. Salman and
the family came to know about it only when
he was summoned to be interrogated. Now
they're waiting for Arbaaz to tell them
details of what happened. No one in the
family will persuade Arbaaz to talk. The
family lives together. But each member is
given space to what he wants, says the
friend.
None of Salman's friends will speak to him
about this unsavoury controversy which
has raised its ugly head from nowhere.
"They don't know what hit them. I think
neither Salim Saab nor Salman has
interfered with Arbaaz's life. The very public
breakup with his wife Malaika Arora and his
subsequent association with another
woman...I don't think anyone in the family
was happy with this. Now this latest
controversy is quite a setback, says the
friend.
With Salman Khan currently out in the public
domain promoting his new film it would be
hard for the usually outspoken actor to
maintain a stoic silence over his brother's
alleged misdemeanour.
