SAN BRUNO -- Two Peninsula teens were arrested by San Bruno police on suspicion of committing three armed robberies over the course of two days using a kitchen knife and a hammer.
Daly City resident Alexander Leonis, 18, was arrested Sunday near King and Junipero Serra drives in connection with the incidents in and around Commodore Park.
His alleged partner, a 16-year-old San Bruno boy who is not being named because he is a minor, was booked into a juvenile facility three days earlier when officers say they found him in the park with a loaded firearm.
The first robbery occurred at 5:37 p.m. April 7 near the YouTube and Walmart corporate offices on Cherry Avenue. The victim was approached by one of the knife-wielding teens who demanded his laptop computer. The suspect took the computer and ran off toward a nearby apartment complex, police said.
That same night, a man in ¿a restroom at a nearby park was robbed about 9 p.m. by the two suspects, one of them brandishing a hammer, police said.
The pair reportedly robbed a third victim at 10:24 a.m. the next day, when they walked up to a man, brandished a large kitchen knife and demanded his wallet and cellphone, authorities said.
The teens took the man's belongings and ran toward the same apartment complex as in the first crime. It was not immediately known if the teens had a connection to that particular apartment building.
"It's not a dangerous area," said San Bruno police Lt. Troy Fry. "San Bruno in general is not known for real high crime and this is unusual for us to have robberies, much less three."
San Bruno officers monitoring the park April 9 encountered a teen matching the description of the younger suspect about 9:21 p.m, Fry said. He was arrested when officers say they found a loaded firearm in his possession and they later determined he was the suspect for whom they were looking.
Detectives arrested Leonis after various tips led them to his Daly City home, Fry said. The pair was arrested on armed robbery charges and the 16-year-old boy was charged with possessing a loaded handgun.
