A Rockville Centre man is under arrest after stealing more than $100,000 in an investment scheme.

According to the Nassau District Attorney’s Office, Arnulfo Castillo, also known as Alexander Castillo Carias Arnulfo, allegedly took money from victims, promising it would be invested into different real estate properties.

He allegedly used the money on personal items and unrelated business expenses, police said.

Castillo pleaded not guilty to the charges and is expected back in court later this month.
