New Zealand police said Thursday they will not pursue criminal prosecution in relation to a Christchurch building collapse that claimed the lives of 115 people, including 28 Japanese students, during a 2011 earthquake.

Detective Superintendent Peter Read said in a statement that after a "complex, technical investigation" into the collapse of the six-story Canterbury Television Building, the police concluded there was not enough evidence to provide a reasonable prospect of conviction in court.

Kuniaki Kawahata, the principal of a foreign language school in Toyama Prefecture who lost his 20-year-old daughter Kyoko as well as 12 of the school's students in the collapse, said he "can't accept" the outcome.
