Sets of military uniform, police extract and a sworn affidavit for loss of her military identity card were said to have been found with her.
The Public Relations Officer of the brigade, Captain Ademola Adegoke, said Omieh was arrested following a report by her boyfriend.
According to him, Omieh, who resides in Mile 3, Diobu, Port Harcourt, Rivers State, was discovered to be in possession of two pairs of camouflage, camouflage T-shirt and short, one pair of desert boot, one jungle hat and three handsets.
He said the suspect had been parading herself as a soldier attached to the 149 Battalion, but deployed to Joint Task Force, Warri for duty.
Adegoke explained that the suspect's boyfriend, Mr. Collins Jegede, narrated how she met Omieh on a social network where she appeared in military outfit.
Jegede said he wooed her and she paid him a visit in January 2014 in full military uniform.
Jegede was also said to have reciprocated the visit, but was surprised that Onieh lodged him in a hotel at the Ijaiye area of Lagos State instead of 149 Battalion, Ojo Military Barracks, where she had claimed to be working.
Adegoke said, "Jegede reported the case to the officer-in-charge of a military checkpoint at Owo following his suspicion that his girlfriend was a fake soldier."
The suspect admitted that she was fake, adding that it was meant to make ends meet.
She said, "I bought the uniform from Army depot in Zaria. I attended the Nigerian Army depot in Zaria, Kaduna State. I could not continue my education when my father died, so I decided to buy the kits to help me travel to Cotonou, Benin Republic for business with ease."
