Amissah-Arthur was speaking at a mini rally at Bulenga, in the Upper West Region as part of his campaign tour to that region.

He told the NDC supporters that they need to ensure they are safe and healthy so they can vote and secure victory for the NDC in December.

“When we are talking to our NDC members, we know that as the elections are getting close, the people who are going to lose are going to get desperate. And when they get desperate, you never know what they can do.”

“So we are asking our people to exercise patience. Please exercise patience because if you are going to win, you don’t want trouble when you win. You want there to be peace when you win… when the people who are losing get desperate and do desperate things, please exercise patience and use the power of your thumb on 7th December to make sure victory comes to the NDC,” he added.

Hundreds of NDC members were attacked on Sunday near the house of the NPP's presidential candidate, Nana Akufo-Addo.

It is however unclear what triggered the clashes but according to reports, both sides confirmed gunshots and hurling of harmful objects.

Sources said the attack was led by ex-convict Ako Gunn. Ako Gunn was released by President Mahama last month after the Supreme Court had jailed him and two others for threatening the Chief Justice with rape and death.

The NDC embarked on a health walk and it was alleged that the personal security of the Nana Addo fired multiple shots at the NDC members.

It took the intervention of the Nima Police to restore calm. They have also started investigating the matter.
