Calcutta, April 22
The Indian Government has been presented with a little local difficulty in the form of Mr. Mahdi Masud, the newly appointed Deputy High Commissioner of Pakistan in Calcutta, who arrived here late last night to take up his post.

Mr. Masud's predecessor, Mr. Hossain Ali, who proclaimed his allegiance to the "Democratic Republic of Bangla Desh" earlier this week and ran up the rebel flag is still in the High Commission building, which from a legal point of view, presumably remains the property of the Government of Pakistan.

Several hotels in Calcutta refused accommodation to Mr. Masud for fear of incurring the wrath of some of the millions of West Bengalis here who are deeply involved emotionally in the Bangla Desh movement. This prudence proved justified.

The Hindustan International hotel, where a room was eventually found for Mr. Masud, was the target this morning of an angry demonstration by about 100 people. A few windows were broken and one or two persons injured before police restored order with tear gas and moderate use of force.

Temporary accommodation was hurriedly arranged for Mr. Masud in a building belonging to the Orissa state Government.

Mr. Masud told journalists upon his arrival at the airport last night that the present occupants of the Deputy High Commission building no longer represented the Pakistan Government and that it was, therefore, the "duty of the host Government to see that the property is returned to its rightful owner".

He is likely to be disappointed on that score. The Indian Government would almost certainly provoke serious riots here if it asked Mr Ali and his group of Bangla Desh supporters to vacate the High Commission premises. In the meantime, there is serious concern about the fate of some 270,000 refugees.
