Ten people suspected of belonging to the radical Islamist sect, Boko Haram have been arrested in Northern Nigeria in recent days.

Seven of them are suspected to be behind a spate of murders targeting policemen.

Three of them are among the hundreds of inmates that escaped when suspected Islamists attacked a jail last week.

More than 700 prisoners including around 100 alleged sect members were freed in a daring attack staged on September, 7 by suspected Boko Haram on the Bauchi state prison in Northern Nigeria. Five people including a military, police officers and other security personnel lost their lives.

The Islamist sect last year launched an uprising in and around Borno's state capital, Maiduguri in the northern part of Nigeria before it was quelled by a military and police assault.

At least 15 people including security personnel have been slain in the Northern region of Nigeria in recent weeks with six of them killed in two days this week. Previous nine murders had been staged by motorcycle riding gunmen mostly in Maiduguri in recent weeks.
