Police arrested 49 people in different districts on charges of vandalism during Monday's pro-Palestine demonstrations, the Chief Adviser's Press Wing said in a statement yesterday.

The attacks on shops were a "serious threat to public safety and the rule of law", said the statement.

Two cases have been filed over the matter, it added. "Further investigations are underway, and additional cases are being filed against those responsible for the reprehensible acts."

Police have raided multiple locations and are analysing video footage to identify suspects, it said.

The government urges people to come forward if they have any information that could lead to the arrest of the suspects, it added.

Groups of rowdy people vandalised and looted shops, restaurants and shoe stores in Sylhet, Chattogram, Cox's Bazar, Khulna, Gazipur, and Bogura during Gaza solidarity processions on Monday.

Home Adviser Jahangir Alam Chowdhury yesterday warned of tough action against those involved.

"We will be vigilant and prevent the recurrence of such incidents," he told reporters at the Secretariat.

Responding to a question, the home adviser said the attack on various shops and business establishments was not preplanned, BSS reports.
