Police in Los Angeles seized more than 2,800 boxes of stolen LEGO sets from a 71-year-old man's home Wednesday, authorities said.

Officers arrested 71-year-old Richard Siegel and his alleged accomplice, 39-year-old Blanca Gudino, after raiding the elderly man's Long Beach home, according to the Los Angeles Police Department.

The individual boxes have a retail value ranging from $20 to well over $1,000, police said.

Detectives started investigating the case after a retailer in San Pedro identified Gudino as the suspect who had allegedly robbed them several times last December.
