Six people have been removed from the Sydney Cricket Ground on day four of the third test between Australia and India in Sydney.

Play was suspended for eight minutes before tea on Sunday as umpires and security guards attended the boundary area before the six were ejected from the venue by New South Wales Police.

Following the incident, Cricket Australia released a statement on the alleged racist abuse of the India team by a section of the SCG crowd on Saturday.

India’s Mohammed Siraj stopped play on day three to issue a complaint while fielding on the boundary during the afternoon session.

Cricket Austrlia confirmed the incident on Sunday while issuing their statement, although it is not known whether the incident on Sunday was related to racist abuse.

"Cricket Australia condemns in the strongest terms possible all discriminatory behaviour," said Sean Carroll, Cricket Australia’s Head of Integrity and Security, in the statement.

"If you engage in racist abuse, you are not welcome in Australian cricket.

"CA is awaiting the outcome of the International Cricket Council’s investigation into the matter reported at the SCG on Saturday.

"Once those responsible are identified, CA will take the strongest measures possible under our Anti-Harassment Code, including lengthy bans, further sanctions and referral to NSW Police.

"As series hosts, we unreservedly apologise to our friends in the Indian cricket team and assure them we will prosecute the matter to its fullest extent."
