Osoru was on her way to Ewanga Sub-county on Saturday when she was kidnapped and assaulted by the suspects.
Ewanga elders had summoned leaders to get their view on a recent letter by ministry of Local Government permanent secretary that the sub-county be transferred to Yumbe district.
The mob dug a hole in the middle of the road near Ariwa Sub-county where the MP was kidnapped and assaulted.
According to Osoru, her kidnappers took away the car key after blaming her and other people for trying to take away Ewanga Sub-county from Yumbe district.
She further noted that they threatened to kill her if she said anything more.
Osoru and her colleagues were reportedly driven off and abandoned at Odravu Sub-county headquarters in Yumbe district, about 15km South of Yumbe district headquarters.
They then used boda-boda motorcycles to Yumbe central police station from where they recorded statements.
