Three men have been charged in connection with burglaries committed in the county where Asian jewellery was targeted.
The men aged 39, 30 and 35, and of South American origin, have been remanded in custody after being charged with conspiracy to burgle, possession of fraudulent IDs, possession of class A drugs and dangerous driving.
The arrests were made in Leicestershire on Thursday afternoon as a result of intelligence received, ANPR enquiries and joint-working with other forces.
The three men are due to appear in Northampton Crown Court on Thursday, December 13.
Detectives investigating a string of burglaries targeting Asian families for gold arrested a 23-year-old man from Northampton last month.
He was arrested at the end of last month and charged with burglary and converting stolen property.
Asian men began patrolling the streets of Northampton last month following an alarming number of break-ins across areas of the town.
Earlier in October a man from Leicestershire was arrested in connection with a burglary on September 8, in Hinton Road, Northampton, where a quantity of jewellery was stolen.
He is due to appear in court later this month.
