MILWAUKEE (CBS 58) -- New concerns this week about safety on Milwaukee County buses after two attacks.
On Thursday, the head of the Bus Drivers' Union says he talked about security for drivers and passengers with Sheriff Earnell Lucas.
Union President James Macon says he asked the Sheriff about the possibility of patrols on the buses but was told because of a manpower shortage, that may be difficult.
The Sheriff said, however, that he's willing to help.
The Union leader is suggesting a range of alternative solutions including a proposal to arm bus drivers who are worried about their safety.
"I have nightmares every day because I'm wondering if I'm gonna get attacked the next day. We are wondering if we're gonna get attacked for asking for the bus fare," said bus driver Michael Brown.
Drivers spoke on Tuesday at a court hearing for Betty Roberts who is accused of attacking and stabbing a driver who asked her for bus fare.
Since that incident, another driver was punched by a man who had asked if he could ride the bus for free.
