A man is being questioned in connection with the fatal shooting of UnitedHealthcare CEO Brian Thompson, according to Sky News’ US partner NBC News.

A man in central Pennsylvania drew the attention of investigators because he was found with a similar gun to the one used in last week’s shooting in New York City, NBC sources say.

Mr Thompson was shot dead outside a Manhattan hotel on Wednesday morning, while he was on the way to the company’s annual conference.

The shooting sparked a citywide manhunt.
