Police on Wednesday searched eight offices and facilities related to the Aum Shinrikyo cult's splinter group for allegedly running a travel agency without proper registration.

Investigative sources said the group, called Hikari no Wa (The Circle of Rainbow Light), is suspected of planning and running a tour package in May that it described as a "pilgrimage," although the group had not been registered as a travel agency.

Operating such a business without proper registration would be a violation of the travel agency law.
