Boko Haram’s seven-year battle to create an Islamic state has forced thousands from their homes.
The deployment of the officers, drawn from various divisions, is also to “dig out true happenings” in the camps, Mr Chukwu told the Nigerian News Agency.
President Muhammadu Buhari said he was “worried” and “shocked” about the HRW report and ordered an investigation into the alleged abuses.
The HRW report said women and girls had been coerced into sex and abandoned when they became pregnant.
“It is disgraceful and outrageous that people who should protect these women and girls are attacking and abusing them,” said HRW’s Mausi Segun.
The group blamed the vulnerability of women – many of whom are widows and unaccompanied orphans – on irregular supplies of food, clothing, medicine and other essentials in internally displaced camps in the Borno state capital, Maiduguri.
