Thieves have stolen the lighting system for one of the runways at Nigeria's busiest airport just months after it was installed, an airport authority spokesman has confirmed to the BBC.
An investigation has now been launched to "arrest the criminals [and] recover what's missing", Yakubu Funtua added.
It is not clear when the system was taken from Murtala Muhammed International Airport in Lagos.
But local media reported that airport workers were involved in the theft.
The ground lights were installed in November, ending years of after-dusk restrictions on landing on that wing of the airport.
