Who destroyed Manyapura- capital of a once glorious Hindu kingdom of Western Gangas?

Manne or Manyapura was once a flourishing city. It is located about 60 km north-west of Bengaluru, India's 'Silicon Valley'. In the 8th century it was the royal residence of Sripurusha, king of the Hindu Western Ganga dynasty which ruled for many centuries over Gangapadi- which today is roughly the region of south interior Karnataka state. Their capital was at Talakadu, hence they are also known as Talakadu Gangas.

In early 11th century CE it was destroyed in an invasion by Rajendra Chola, another powerful Hindu King, who ruled not only south India but many parts of south-east Asia. Due to his destruction of the Talakadu Ganga dynasty (or perhaps due to his expedition to River Ganga in north India), Rajendra Chola was titled 'Gangaikonda Cholan' (the Chola who captured Gangas).
