A quick police response and a citizen standing up for themselves has led to an arrest.
Waterloo Regional Police say a 74-year-old man was leaving his car around 1:00 a.m. Sunday morning in the area of Erb Street East and Moore Avenue when a 27-year-old man tried to take his keys, then cellphone.
The 74-year-old resisted and called for help, but not before he was hit in the head by the suspect.
Police say the suspect was quickly arrested.
A 27-year-old man from Mississauga is now facing a robbery charge.
