Next Digital founder Jimmy Lai and two of his senior executives have been charged with fraud, after they reported back to police on Wednesday after getting arrested earlier.

They are due to appear at West Kowloon Court tomorrow.

Apple Daily says the three are accused of using Next Digital's headquarters in Tseung Kwan O for purposes not permitted by the lease.

The outspoken media mogul was arrested in August, and was initially accused of breaching the national security law though he hasn’t been charged.

The same day, around 200 police officers raided the Next Digital building and arrested several senior executives of the media company, along with Lai’s two sons.

Seven others who also reported back to police on Wednesday were granted bail and told to return in March next year.

Police say their National Security Department is still investigating the case.
