OAKLAND -- A parent who had just dropped her child off at school and a teacher arriving for an interview were robbed at gunpoint of their purses Thursday morning outside two East Oakland elementary schools.

Police believe the same suspects were involved in both robberies. No children were present during the incidents, which happened at schools a few miles apart.

The first robbery happened about 8:30 a.m. outside Manzanita Elementary school, 2409 E. 27th St.

Police said the victim had just dropped her child off and was walking back to her car when a man took her purse at gunpoint and fled in a vehicle containing two other men.

The woman's purse, minus her iPhone, cash and credit cards, was found a short time later at the intersection of 21st Avenue and East 22nd Street.

The second incident occurred at 9:05 a.m., when a special-education teacher was robbed of her purse outside Franklin Elementary School, 915 Foothill Blvd.

Police said the woman had just gotten off a bus and was walking on the Ninth Avenue side of the school on her way for a job interview when a gunman took her purse and fled in a car.

Her purse has not been recovered.
