It's been five days since a nanny cam caught a man barging into a Millburn home where he  violently beat a mother in front of her 3-year-old daughter, stealing jewelry in the process. A reward of $20,000 is now being offered for information leading to the arrest and conviction of the suspect.

The video was released in hopes of identifying and finding the suspect, but authorities have had no such luck yet.

An earlier $5,000 reward has been increased to $20,000 today, in return for information leading to an arrest and conviction of the man on camera.

"We're hoping that entices someone to come forward and give us a hand," said Millburn Police Chief Gregory Weber.

Weber described Millburn as a "quiet town," saying he would have to go back at least 15 years to find a situation as violent as the nanny cam attack.

According to police, the home was not equipped with a security system. The attacker allegedly kicked in a deadbolt-locked door.
