An electoral enquiry committee has found some proof to back up the allegation that Awami League lawmaker Shamim Osman threatened a police officer at the time of Narayanganj-5 by-election on June 26.
Shamim Osman allegedly verbally abused and threatened a police officer, Bashir Uddin, after he had foiled an attempt by Osman supporters to occupy a polling station during the voting hours.
The probe committee has recommended further investigation into the allegation before making any decision regarding the matter, according to a probe report submitted to the Election Commission.
On June 29, the returning officer appointed by the EC asked the electoral committee to investigate the matter.
EC's acting secretary Sirazul Islam on the day said the enquiry committee would submit a report within three days as per the electoral law. However, the report was submitted on July 9.
The report will be placed at the EC's next meeting, a senior assistant secretary of the EC Secretariat told The Daily Star.
The commission will then decide on the next course of action, he added.
Selim Osman, brother of Shamim Osman, won the by-election, in which huge fake votes were cast by supporters of Selim Osman, according to news reports and election observers.
The constituency fell vacant after their brother Nasim Osman died on April 30.
