Those affected by an early December cyber VTech hack might finally be getting their justice. A 21-year-old man was arrested on Tuesday by British police in connection with a computer hack of VTech earlier this year, according to Bloomberg. The man was arrested as part of a cyber-crime probe.

The children's VTech holdings had data of more than 6.4 million children exposed in a computer hack, according to Reuters. Experts believe that this was the largest data breach of personal data pertaining to children.

No financial data was released, but personal information such as names, birth dates, and gender were released, according to Bloomberg.

"We are still at the early stages of the investigation and there is still much work to be done. We will continue to work closely with our partners to identify those who commit offences and hold them to account," said head of the cyber crime unit, Craig Jones, according to the Wall Street Journal.

The man was arrested by officers in the South East Regional Organized Crime Unit in Bracknell ,which is about 30 miles west of London, according to the Wall Street Journal.

Not much information has been released, but police collected a number of electronic items from the suspect's residence, according to Reuters.
