LAGOS, March 6, 2016 (AFP) - Three secondary school students who were kidnapped from their school in Nigeria's biggest city, Lagos, have been found, police told AFP on Sunday (March 6).

"We have rescued the three girls in the early hours of today (Sunday)... in Igbokuta village," said Lagos State police spokesman Dolapo Badmus.

"The girls are in good condition. Some of the suspected kidnappers were arrested when our policemen stormed the location."

The three girls were seized from a dormitory last Monday at the Babington Macaulay Junior Seminary School in the eastern suburb of Ikorodu.

The abduction sparked a massive search for the teenagers and prompted the state government to tighten security at schools across the megacity, which is home to some 20 million people.

Igbokuta village is some 15km from the school and about 25km from Ikorodu.

Police have previously refused to comment on local media reports of demands for a 200-million-naira (S$1.4 million) ransom.

Ms Badmus said investigations were continuing and did not rule out further arrests.

Abductions from schools are rare in Lagos, although kidnapping for ransom by armed criminals is common in southern states.
