A teenager who allegedly assaulted and robbed two elderly men, one of whom claims he was followed into his own backyard, has been arrested and charged.

Police charged a 14-year-old boy with the alleged assault and robbery of a 74-year-old-man in Donvale on December 12, along with a similar alleged attack on an 82-year-old man in Vermont South the day before.

The 74-year-old man got off a bus on Carbine Street about 4pm when the alleged attacker followed him.

He was approached from behind and allegedly lifted off the ground, punched then robbed.
