OAKLAND (CBS SF) — An Oakland woman was charged with attempted murder and three other felonies Monday for allegedly stabbing a 12-year-old boy and robbing two customers at a San Leandro bank on Monday, prosecutors said.

Iyona Hammond, 32, was arraigned in Alameda County Superior Court in Hayward today in connection with the incident at the Wells Fargo Bank at 1298 E. 14th St. at about 11:30 a.m. on Monday and is scheduled to return to court on June 16 to enter a plea.

According to San Leandro police spokesman Lt. Robert McManus, the boy was sitting in a chair in the bank’s lobby, waiting for his grandmother to complete a banking transaction, when Hammond stabbed him three times in the back almost immediately after she entered the bank at 11:30 a.m.

Witnesses told police that the attack was “random and unprovoked,” San Leandro police Officer Zachary Sampson wrote in a probable cause statement.

Witnesses said Hammond then stole money and bank cards from two customers, Sampson said.

The two customers didn’t confront Hammond after she stole their property because they “feared for their lives,” Sampson wrote.

Officers found Hammond nearby at the corner of East 14th Street and Estudillo Avenue, with blood on her hands and holding a pair of scissors in her right hand, according to Sampson.

The boy was rushed to UCSF Benioff Children’s Hospital Oakland and had to undergo surgery to treat his wounds but he has been discharged, McManus said.

In addition to murder, Hammond was charged with corporal injury to a child and two counts of second-degree robbery.

Prosecutors also allege that she has a prior conviction for assault with a deadly weapon in Alameda County in 2005.
