(AP) — Authorities are investigating the theft of gasoline from vans with full tanks ready for services at an Omaha church.

Officials at Glad Tidings Church say the four vans were in the parking lot the night before Sunday services. They were discovered the next morning with doors open and gas caps missing. They estimate that 40 gallons of gas was siphoned from the vans.

The church is considering adding more lighting in the parking lot to combat its vandalism problem.
