Some security experts have called for a thorough and unbiased investigation into the recent   killing of three police officers in Taraba by men of the Nigerian Army.

The three detectives in the Inspector-General of Police Response Team and one civilian were  killed by army personnel in Ibi, Taraba, after they allegedly arrested one Alhaji Hamisu indicted in a series of high profile kidnap incidents in the state.

The Army said that the killing was in error, adding that its men mistook the detectives for kidnappers.

The Police, however, claimed that Army knew that the deceased were police detectives and shot them at close range. During the killing of the officers and civilian, the suspected kidnapper allegedly escaped.

The Nigerian Army and the Nigeria Police have consequently set up a Joint Investigation Panel headed by DIG Mike Ogbizi, in-charge of Criminal Investigation Department.
