Tirupati: A bomb disposal squad, with the help of sniffer dogs, unearthed nearly one dozen claymore mines planted in a stretch of 200 metres, in a gap of 10 feet each, on the second ghat road leading to the Lord Venkateswara shrine, on October 2.

Police sources said the mines might have been planted about six months ago, with a view to wipe out the entire convoy of the Andhra Pradesh Chief Minister N Chandrababu Naidu.

Naidu usually visited the shrine to offer "silk vastrams" to the Lord on the eve "Garuda seva" annually.

The sources said only four mines went off on October 1. It all of them had exploded then it could have been disastrous to the entire convoy.

The mines have been removed and had been taken to an undisclosed place.
