A former SoftBank Corp. employee has been arrested on suspicion of illegally disclosing 5G trade secrets to his new employer, Rakuten Mobile Inc., as it was preparing to launch its own mobile network.
The Tokyo Metropolitan Police Department on Tuesday arrested Kuniaki Aiba, 45, on suspicion of leaking secret information in breach of a law preventing unfair competition.
Aiba is suspected of having transferred trade secrets from SoftBank by emailing information on the company's 5G technology to his own account on Dec. 31, 2019, when he was still working for SoftBank, police said.
