NEW DELHI, April (Reuters) —The Pakistan radio said to night that Pakistan had decided to close down the Deputy High Commission office in Calcutta and had asked India to close her Deputy High Commission office in Dacca.

The radio, quoting an announcement in the Pakistan capital, Islamabad, said the closings would take effect Monday.

Pakistan's move follows angry demonstrations in Calcutta against the new Deputy High Commissioner, appointed after the previous holder of the post switched allegiance to the Bangla Desh independence movement in East Pakistan. Bangla Desh is Bengali for Bengal Nation.

Earlier today Pakistan accused the Indian Government of failing to prevent what she termed unprovoked and violent demonstrations against the new Deputy High Commissioner, Mandi Masud.

It also protested that the Indian Government had not taken action to remove the former Deputy High Commissioner from the mission premises.
