Douala: Cameroon`s state broadcaster says 15 gunmen stormed a bank with grenades and then took off in a high-speed boat chase that turned into a gunbattle.
The broadcaster said late Sunday that at least seven people were killed, and bank officials say the robbers made off with about USD 400,000 in cash.
Two of the gunmen were arrested after the attack in the seaside city of Douala on Saturday.
Local official Fai Yengo Francis says one soldier died following the speedboat chase. A robber and five others also were killed.
Army official Sona Mbengue says the incident resembles another one three years ago that officials blamed on pirates from neighboring Nigeria. Pirate attacks have risen around Nigeria in recent years.
