(AP) — Lincoln police are investigating the theft of $135,000 from an aircraft sales company.

The Lincoln Police Department says Duncan Aviation reported the theft Thursday after a shareholder said someone hacked into his email account and moved money within several bank transactions in late September and early October.

Police did not explain why $135,000 of company money was in the shareholder’s account. Company officials declined to comment.

Police are working with fraud investigators at the banks where the money was transferred. Officer Katie Flood declined to say whether authorities had a suspect.
