BNP leader Ruhul Kabir Rizvi has expressed concerns over the petrol bomb found in the Bangabandhu Sheikh Mujib University (BSMMU) on Thursday.
The party's senior joint secretary general suspects the bomb was placed with support 'from the top', according to bdnews24.com.
Speaking at a media briefing on Friday, Rizvi said, "How did a petrol bomb end up at BSMMU under such tight security?"
"This couldn't have happened without support or a blueprint from the top. This is what the people suspect."
On Thursday, a petrol bomb was found in front of the registrar's room on the third floor of BSMMU's administrative building.
BNP has called for tighter security at the hospital as the party's incarcerated chairperson Khaleda Zia is currently undergoing treatment in a cabin block.
"When news of the petrol bomb surfaced, many began asking us what the situation is. Everyone was shocked since the national leader Khaleda Zia is receiving treatment there."
Demanding the proper treatment and release of Khaleda, Rizvi said, "I've said before that this is all part of a big master plan. It's difficult to gage the government's intentions. Our national leader isn't well and so proper treatment for her at the hospital must be ensured."
