It is not clear who is behind the latest shooting in the region, but it is suspected that the Somali militant Islamist group al-Shabab is responsible.
The militant group mounted a number of attacks in the region early last month, which left 60 people dead.
Hindi is 15km (nine miles) from Lamu and close to the town of Mpeketoni, which was nearly destroyed in one of the attacks last month.
Lamu island is a well-known tourist resort, however, the attacks happened on the mainland, in Lamu County.
