"Respect your elders" is evidently not a value that's held by several San Francisco muggers (that, and "don't steal things or hit people"), as two men occupying a more senior demographic were brutally beaten and robbed Tuesday in separate attacks.

The first was a brazen mid-day assault and theft, when at 12:10 in the afternoon a man in his 40s and a woman in her 30s approached a 78-year-old man from behind near Eddy and Leavenworth Streets.

According to the Ex, the approaching man started hitting the elderly fellow with his own cane, as the woman pepper sprayed the older gent in the face.

They went through the victim's pockets, stole his cash, and fled. At publication time, the duo is still on the loose.

The victim was taken to San Francisco General Hospital to be treated for his injuries, and is expected to recover.

Just a few hours later, and (depending on how you travel) four or five blocks away, a 56-year-old man was sitting in a coffee shop at Fourth and Mission Streets, which is near the Metreon.

At around 7 p.m., a teen (witnesses say he looked to be around 16 years old) grabbed a cell phone from the man's hand and ran out, Bay City News reports.

When the man chased the thief, he was jumped by a group of six juveniles, who "punched and kicked the man in his head and body" and shocked him with a stun gun.

The six deplorable teens took off after that, but officers from the San Francisco Police Department were able to track one down and arrest him. The other five, however, remain at large at publication time.

The beaten man "suffered multiple injuries to his head and body," but declined treatment, police say.

As always, SFPD asks that if you know anything about either crime, that you call their anonymous tip line at 415-575-4444.
