TIRANA, Albania (AP) — Albanian prosecutors have confiscated the properties of a man who was shot dead during an airport robbery that saw armed men take a large sum of cash as it was loaded onto a passenger plane.

Prosecutors said Friday they seized 300,000 euros ($340,000) as well as apartments, a villa and nine vehicles owned by Admir Murataj’s family. Murataj was killed Tuesday in an exchange of fire with police at Albania’s only international airport.

Murataj is one of a group of men accused of stealing about 7 million euros ($7.8 million) in three bank money robberies since 2015.

Authorities have sent military and regular police to boost security at the airport following Tuesday’s robbery, where Interior Minister Sander Lleshaj said 5 million euros ($5.6 million) were stolen.
