Police on Friday fired teargas and live bullets before arresting Lwemiyaga County MP Theodore Ssekikubo.
This was during a weekly cattle market in Sembabule district. Police accused Ssekikubo of defying quarantine imposed in the area.
Ssekikubo and livestock farmers attempted to forcefully enter Lwemiyaga Cattle Market which police closed last week.
Police under the command of Masaka Regional Police Commander, Enock Abaine, intercepted them arresting Ssekikubo and six other herdsmen.
They were detained at Masaka Regional Police Station on the charge of defying quarantine which is contrary to Animal Diseases (Amendment) Act 2005.
On December 20, the group succeeded and sold over 100 cows at the market in defiance of a quarantine declared by veterinary officials in response to reported outbreak of Foot and Mouth Disease (FMD).
A person who contravenes such rules is liable to a fine not exceeding Shs100, 000 or imprisonment for a period not exceeding a month or both.
