The crew onboard the bulker causing a pollution disaster after grounding off Mauritius may have sailed too close to the coastline in search of an internet connection, Japanese media are reporting.

According to the unconfirmed reports, which cite local news outlet Lexpress.mu, the 20-man crew diverted the 203,000-dwt Wakashio (built 2007) to secure a connection as part of the birthday celebrations of one of the seafarers aboard.
