Terror threat continued to stalk the diamond city of Surat on Wednesday as three more live bombs were found in busy localities, one of them shortly after Gujarat Chief Minister Narendra Modi's visit.

The bombs found on Wednesday were similar to the 18 found on Tuesday from in and around Varacha, where several diamond processing units are located, police said.

An explosive was detected at Baroda Prestige Market in Varacha area, about 500 metres from Labeshwar Chowk where Modi had gone for a first-hand assessment.

Another bomb was found in Nana Varacha area hanging from a tree close to the Surat Municipal Corporation swimming pool.

The third bomb was located inside a bag filled with clothes at Hirabazar area of Mahidharpura locality, police said.

Once again it was a local resident, who informed police about the bomb.

With this, the total number of live bombs recovered in the city in the last three days rose to 23.

The Bomb Disposal Squad has been on its toes the whole day with many hoax calls from different parts of the city, they said.

The diamond city has been on the terror target ever since the serial blasts in Ahmedabad on July 26, which has claimed 53 lives and injured over 140 people.

Schools, colleges, parks and shopping malls remained closed in the city following the recovery of bombs and people preferred to remain indoors.

On Monday, the bomb disposal squad successfully defused a live bomb in a residential area of Varacha and on Sunday the police defused a bomb near a hospital in New Citylight area.

Police also recovered two explosive-laden cars from two different parts of the city on Sunday.
