The police authorities asked people not to heed rumours and fake news, and urged to call the national emergency helpline 999 to verify and crosscheck the authenticity of information, said a press release on Monday.
The call came five days after a person named Abu Yunus Md Shahid-un-Nabi had been lynched and burnt over rumours of dishonouring the Quran in Lalmonirhat.
The police authorities also asked people not to take the law into own hands.
In the note, Police Headquarters assistant inspector general for media Sohel Rana said that they would be strict in preventing such illegal activities.
The government has repeatedly instructed and warned people against rumours after the Lalmonirhat lynching.
The government also warned them of tough action for violating its order in a statement of the Press Information Department on Sunday.
