Chaos rocked Msambweni by-election after a confrontation broke between Mvita Mp Abdullswamad sheriff and Nyali Mp Mohamed Ali.
The confrontation occurred at ODM candidate Omar Boga’s home area in Mworoni primary school, Ukunda township over bribery claims.
The exercise has seen political supremacy battles between ODM party flag bearer Omar Boga and independent candidate Feisal Bader who has been fully backed by Deputy President William Ruto.
Despite the fact that the exercise was being carried out smoothly, there were counter-accusations of bribery tendencies between the two political bigwigs.
But the Electoral commission in Kwale has not confirmed any malpractices.
Speaking after casting his vote at 8 am at Jogoo grounds in Ukunda township, Boga said chaos erupted after Ali was caught red-handed buying votes through his agent.
However, Bader dismissed the allegations.
Polls will close at 5 pm before the vote count begins.
Meanwhile former Machakos senator Johnston Muthama was arrested by police in Msambweni.
Muthama was later driven to Mombasa port police station under tight security.
