TAMPA — Authorities are investigating a string of robberies they believe may be related, police said.
In three of the cases, the robber had a shirt covering his face or wrapped around his head.
On the night of May 29, a man knocked a woman to the ground in the 4600 block of W Gray Street and searched her pockets. The man ran away when the woman was able to strike his head with a gallon water jug.
Around 11 p.m. May 23, a 74-year-old man was knocked to the ground in the 1800 block of West Shore Boulevard N. The man's assailant took money and a hearing aid.
The first two robberies occurred on May 22. At 10:35 p.m., a man pushed a woman to the ground near Lois Avenue N and W North A Street and stole her purse.
And at 10:20 p.m. near North B Street and Hubert Avenue N, a man was shocked with a stun gun, and the robber fled with the man's iPhone.
