TILTON, N.H. — Police in Tilton, N.H., say they believe all of the suspects involved in a jewelry store robbery last year have been arrested.

Robbers made off with more than $200,000 in merchandise at the Kay Jewelers store at the Tanger Outlets on Nov. 4. Three men wearing Halloween masks from the movie “Scream” threatened customers with a gun and smashed jewelry cases with a hammer before making off with the jewelry.

Tilton Police Chief Robert Cormier says four people from the Los Angeles area have been arrested over the last few months.

He told WMUR-TV (http://bit.ly/SYOJ12) a break in the case came when two people who saw news coverage of the robbery found one of the masks. They called police, who were able to gather DNA evidence.
