Four Africans barged into my room at 7am. They objected to my interference and administered electric shocks to me using a water heater coil, stabbed me in the head, hands and back. They dragged me out and bundled me into the boot of their car, saying they would kill me,” Lonja said.Police said they have arrested two men, Michael Williams and Robert Osara , both from Nigeria and aged about 25 years. “A few others are at large and we will arrest them soon,” a police officer said.Police later learnt that Lonja had on Wednesday stabbed a friend, Kparagume from Nigeria, during the altercation.
