Mumbai police faced some anxious moments hours before the high-voltage World Cup final match between India and Sri Lanka began as its official website had received an email stating bombs were planted inside the stadium, but thorough search did not find any explosive.

It was a prank email sent on April 1 night to make the security agencies "April fool", a senior police official said.

At about 11.30 pm on April 1, the email was received at Mumbai police's official website stating that 30 bombs were placed inside the stadium to disrupt the high-octane clash, the official said.

The email has been traced to a server in Norway, while the sender's IP address had been traced to a country in Western Europe, the officer said adding that Cyber Cell of the city police began its probe in the case.

When contacted, Deputy Police Commissioner (Operations) Rajkumar Vhatkar said, "The email was received a day before the match but nothing suspicious was found during the anti-sabotage operation. We knew no explosives would be found as security checking had been done several times in the stadium, but we did not take the threat lightly."

The email was seen on the morning of April 2 following which all the security agencies including National Security Guards, Force One, CISF were alerted, police said.

The special Bomb Detection and Disposal Squad for the stadium searched the ground thoroughly for a few hours but nothing suspicious was found, an senior police officer said.
