"Holy Child School, run by Catholic nuns in Delhi... Attacked. Vandalized...Please. Give peace a chance," O'Brien tweeted.
"Spoke to authorities in Delhi. Security CCTV system first destroyed before school was vandalised. Suggests attack well planned," he further said in his tweeter feed.
On the Prime Minister summoning the Delhi Police Commissioner today and directing him to come down hard against those involved in such attacks, O'Brien told PTI, "Let us see some progress in the SIT probe which was set up after a church was burnt in Delhi in December last year".
"The Christian community is concerned over the repeated attack on churches," O'Brien, who is the chief whip of the Trinamool Congress parliamentary party in the Rajya Sabha, said.
