David Singh

Captain David Singh is a police captain of the Central City Police Department.

Biography
After a bank was robbed, Singh was present at the crime scene. He was annoyed at Barry Allen's lateness, but allowed him to proceed with surveying the crime scene.

When Barry Allen returned back to work following his coma, Singh requested DNA evidence from him in regards to the Hotchkiss case. Barry promised to bring it right to him. Later that day, he sent Barry, Eddie Thawne and Joe West to the scene of a homicide.

At the scene of a robbery, although there only appeared to be one person, Barry determined that there was in fact six, all with the same shoe size, which he noted to funnily enough be the same as Captain Singh's, prompting him to apologize and reassure that obviously Singh was not a suspect. David and Detective Thawne promptly walked away. Later in the investigation, after the robber, identified as Danton Black, began shooting up a Stagg Industries warehouse, Singh and the rest of the department suited up to backup the two detectives already there.

Singh approached Barry looking for the "fiber analysis on the Orloff case". Barry told the captain that he'd finished it and promised to bring it down for him, though Singh was skeptical that Barry would be quick, so he decided to tag along behind, along with Caitlin Snow. He queried who she was and she claimed to be Barry's personal physician. As they reached his lab, Barry handed Captain Singh his findings and Singh surveyed the lab, telling him to clean it up (unbeknownst to him, Barry had used his super speed to put together the case file).

After a failed attempt to rob the Kahndaq Dynasty diamond, Singh was at the scene, where he was told by a guard there were three men involved. When Barry arrived, Barry corrected Singh that there were actually four men. After Barry gave his reasoning, Singh sarcastically thanked Barry for his insight.

He mentioned that a healthy diet was being inflicted and enforced upon him by his boyfriend, though it is not completely clear whether or not he was actually being sarcastic to antagonize Joe. He later allowed an adamant and pushy Eddie Thawne to begin a task force against The Flash.

After the return of Leonard Snart, Captain Singh allowed S.T.A.R. Labs help out the police force, by designing an ice-proof ballistics shield. Cisco Ramon demonstrated the shield using a dummy, but Singh was skeptical that it would work well with real officers. A while later, Singh attended the scene of a fight between Captain Cold and Heat Wave, learning of the legitimate existence of The Flash. He attempted to stop Detective Thawne from helping out The Flash, but was unable to. However, Eddie survived and was rushed away from the fight by The Flash. Before long, the two men were stopped and handcuffed. They were led through the police precinct by Captain Singh, who had to help intervene when Rory accidentally came loose from the police escorting him.

Personality
David takes his job as a police captain very seriously. He has a dislike for Barry Allen who he believes is lazy and sloppy, due to the latter always being late, unaware that there is a situation that causes him to be late. He can be rude and disrespectful towards Barry (for no apparent reason) whenever there's a case going on. However, David can't handle a taste of his own medicine, when Barry snapped at him for (although he was under the influence of Roy Bivolo at the time), for being rude and disrespectful towards him for no apparent reason.
