The man, identified by police as Luzian Andrin Zgraggen, was detained on Saturday after being reported over an Instagram post in which he allegedly used repeated expletives to refer to Nyepi, Bali police spokesman Ariasandy said in a statement late Sunday.

Zgraggen is being investigated for spreading hate speech online, an offence under Indonesia’s updated criminal code that carries a maximum penalty of five years’ imprisonment.

Police said they would confiscate his iPhone as part of the inquiry and question witnesses.Ariasandy did not specify the suspect’s age, in line with common Indonesian practice where some officials use a single name.

Nyepi, observed last Thursday on the island of Bali, is a key religious observance in the Hindu-majority region. The day requires residents and visitors to remain indoors for 24 hours for self-reflection, with work, travel, entertainment and even the use of electricity largely halted.

Indonesia, the world’s largest Muslim-majority country, has stepped up enforcement against behavior deemed offensive or unlawful by foreign visitors.

Bali, a major tourism destination attracting millions of international tourists annually, has seen a series of high-profile incidents involving foreigners in recent months.Last week, authorities arrested two French nationals and an Italian on allegations of producing and distributing pornography, which is prohibited under Indonesian law.

The measures expand enforcement powers under the Hong Kong national security law, introduced by Beijing in 2020 following large-scale pro-democracy protests in the financial hub.

The latest amendments mandate that individuals hand over “any password or other decryption method” needed for police to access electronic devices believed to contain evidence.

The rules apply not only to those under investigation for national security offences but also to individuals who own, possess, or are authorized to access the relevant devices, as well as anyone with knowledge of the required passwords or decryption tools.

Failure to comply constitutes a criminal offence, marking a shift from previous practice, where refusal to unlock devices was not treated as obstruction.The amendments were formulated under the direction of Chief Executive John Lee in coordination with the National Security Commission.

A government spokesperson said the measures aim to ensure that activities endangering national security can be “effectively prevented, suppressed and punished,” while safeguarding the lawful rights and interests of individuals and organizations.

Hong Kong has further strengthened its legal framework with an additional security law enacted in 2024, complementing the broader legislation imposed after the 2019 unrest.
