Members of a Sikh temple in Mill Woods nabbed the people believed to be taking cars while they were inside for morning prayers.
In late March, thieves allegedly walked into the cloakroom of the Gurdwara Sikh Temple, looked for car keys left in coat pockets and then drove off with the vehicles.
After taking two vehicles two mornings in a row, worshippers decided they had enough. They waited in the cloakroom for the culprits to arrive.
"When they entered the room, into the area, then we grabbed them," said Jaspal Bansal.
About seven or eight men detained the suspects until police arrived.
"They tried to run, but we caught them," said Nirmal Singh Bhui.
Two 14-year-olds and a 19-year-old are charged with possession of stolen property and theft over $5,000.
"These youths are known to police and it is a crime of opportunity," said Sgt. Shawn Corrigan from Southeast Division, adding that security video helped police with the investigation.
Temple members are dismayed that anyone would steal from a place of worship.
"This is a holy place," said Bhallan Singh Sidhu. "This is really bad to hear that somebody is stealing."
