The Flash TV series has cast Jesse L. Martin as Detective West.
Martin, known for Law and Order, will co-star along with Grant Gustin who plays Barry Allen.
Detective West is described as a surrogate father to Barry Allen in The Flash TV Series which spins off of Arrow that featured Gustin as the Central City assistant police forensics investigator assisting Oliver Queen.
The mid-season 2 finale of Arrow debuted the accident that gives Barry Allen his powers.
The latest episode of Arrow revealed that Barry Allen is currently in a coma as a result of the accident.
The Flash looks to begin filming soon with no premiere date announced as of yet.
