First Humpback Whale in Hong Kong

A Humpback Whale - first for Hong Kong - was seen in "East Lamma Channel" yesterday (SCM Post reported it today), when also seen nr Po Toi. Seen near Po Toi/Stanley today. Heard of it heading towards Shek O; but also of marine police report re it heading towards Cheung Chau at 7pm.
Big animal, but very big area! - though I may go out to look for it near Cheung Chau in the morning.
