A District of Columbia policewoman who assisted an 85-year-old woman in recovering from a lottery scam was arrested June 14 for stealing money from the same elderly resident, The Washington Examiner reported.

Sgt. Aisha Hackley, 35, helped a Northwest district woman set up a bank account and secure reimbursement for a lottery scam she suffered in December. But at the same time, Hackley allegedly forged $43,055 worth of checks from the woman’s personal bank account.

After the police department’s internal affairs division received a tip from an officer in April, the city filed a lawsuit against Hackley and charged her with first-degree theft.

In the complaint, the former police officer wrote eight checks, six of which used the alias Aisha Jackson, D.C. CBS affiliate WUSA reported. Two checks were made payable to her son, Kevin Jackson.

D.C. police spokeswoman Gwendolyn Crump told the Examiner that Hackley’s police powers have been revoked.

Hackley is the fifth District officer who has been arrested and accused of theft allegations in the past three months.

The Metropolitan Police Department in a statement said it would have no further comment on the case, saying it is now a matter for the courts.

Jackson appeared in D.C. Superior Court on June 14 and is due back June 30 for another hearing.
