WARSAW, Oct 6 (Reuters) - A Polish court decided on

Monday that the Ukrainian diver wanted by Berlin over his

alleged involvement in explosions which damaged the Nord Stream

gas pipeline, must remain in custody for another 40 days.

Volodymyr Z. was detained near Warsaw last Tuesday and the

court decided he would be kept in custody for seven days. The

court decided on Monday to extend his detention while a decision

is made on whether to transfer him to Germany based on a

European arrest warrant.
