Birmingham police tonight announced arrests against four men - three of them teens - in connection with separate carjackings on Birmingham's Southside last week.

Both carjackings happened in the afternoon and one day apart. They also happened only blocks from each other. Police, however, don't believe the two incidents were linked.

Police said they are not releasing details of the cases out of respect for the victims.

Terrell Banks, 18, is charged with first-degree robbery in one of the crimes. Police say he robbed the victim at gunpoint and took a vehicle. His bond is set at $20,000.

According to court records, Banks robbed the victim of a Chevrolet sedan and a cell phone on Jan. 5. Banks was taken into custody Jan. 9, and released on bond Monday, according to court records. He is set to make his first court appearance Feb. 1.

The second case happened the following day about 5 p.m., and guns also were involved. Court records say the victim was robbed of a Ford SUV and a cell phone.

The three men charged in that case are Tyrese Sanders, 20; Robert Prowell, 18, and Damondre Miller, also 18.

Prowell and Miller are both charged with first-degree robbery. Their bond is set at $20,000. Both remained in the Jefferson County Jail Tuesday evening.

Sanders is charged with first-degree stolen property. He was released Monday on $20,000 bond.
