The UN office in Bangladesh has expressed concerns over the attacks on independent candidate and YouTuber Ashraful Hossen Alom, better known as Hero Alom, during the Monday's election in Dhaka-17 constituency.

"The @UNinBangladesh is concerned over the attack on independent MP candidate Ashraful Alom during the Dhaka-17 by-poll. The fundamental human right of everyone to participate in elections without violence should be guaranteed and protected," Gwyn Lewis, UN resident coordinator in Dhaka tweeted.

Earlier, the US also sought an investigation into reports of violence over attacks on Hero Alom.

The US wants the investigation to be conducted "thoroughly, transparently, and impartially, and to hold the perpetrators of violence to account.”

There have been no reports of violence throughout the day, except the attacks on Hero Alom. Police arrested four perosns related to the incident.

Ruling Awami League candidate Mohammad A Arafat, who made a landslide victory, condemned the attack and demanded exemplary punishment against those miscreants who were involved in this incident. 

“If the attackers were from our party, they will get organizational punishment and law enforcement agencies will do their job," he said.

He urged the media personals to help the law enforcement agencies to identify the attackers through the video footages.

As the incident happened just before the ending time of the polls, he said the attack was carried out to make the election questionable as the day-long voting was being conducted peacefully."

The Election Commission and the observers also said that the election was held peacefully.
