A man authorities say robbed other men he lured via social media into meetings with what they thought were women was ordered held on high bail on Monday. 

The Suffolk district attorney’s office says 30-year-old Rakeem Austin, of Boston, is charged with nine armed robberies.

Austin was initially charged with five robberies after allegedly luring men to rendezvous with what they thought were women, then taking their cash and valuables.

But a grand jury investigation developed additional evidence in four more cases.

Austin was previously arraigned on six of the armed robberies in Dorchester Municipal Court. 

According to the district attorney, nine victims arranged to meet up through a dating app, expecting to meet a woman who went by the user name "Lizzy S" or "Candy B." 

At each of the meetings, the victims instead encountered Austin, who, with a handgun, ordered each man to the ground and then stole items including cash, wallets, cell phones and jewelry, according to prosecutors. 

The robberies happened on Oct. 2, 7,14; and Nov. 11 and 21. 

At the time of the robberies, Austin was wearing a GPS monitor while free on bail in a case charging him in connection with a series of breaking and entering incidents. 

Austin is due back in court on April 22.
