Mumbai has been put on high alert after the Intelligence Bureau warned of a terror attack in the financial capital by Students Islamic Movement of India (SIMI) militants. The Mumbai police have sent alert notifications to all the 93 police stations across Mumbai.

SIMI was suspected to have carried out the 10 July low-intensity blast in a parking lot of a police station in Pune. At least five people were injured in the blast that took place near the famous Dagdusheth Halwai Ganesh temple.

The Central agencies had earlier released an alert claiming that the group was planning terror attacks in Maharashtra, Karnataka and Rajasthan. "We suspect that the (Pune) blast was carried out by five of the six SIMI men against whom the central agencies recently released a specific alert stating that the group was planning to carry out strikes in Maharashtra, Karnataka and Rajasthan," The Hindu quoted a senior police officer in an earlier report.

The five SIMI members are believed to be reconnoitering places across Maharashtra ever since their escape from the Khandwa prison in Madhya Pradesh in October 2013.

The Sunday's bomb blast in Bengaluru necessitated beefing up of security across India, especially in major cities such as Mumbai, Pune, Delhi and Kolkata.

India was already on alert following the attack on a Pakistan school and the arrest of the Islamic State twitter account handler Mehdi Masroor Biswas from Bengaluru earlier this month.

The ISIS had threatened the Bengaluru police on Twitter, saying ISIS will take revenge for arresting one of their members. The Karnataka state government has claimed links between Biswas' arrest and 29 December low intensity blast in Bengaluru's Church Street.
