Lestrade

Inspector Lestrade was a detective of Scotland Yard. He came from the old school that was more concerned with making an arrest than amassing evidence.

Biography
In 1885, he unsuccessfully dragged a lake looking for Hatty Doran's body. Dr. John Watson's notes on the case were later written as a story by Arthur Conan Doyle and published in The Strand. In 1887, the Seventh Doctor saw him drinking in the Tank. (PROSE: All-Consuming Fire)

In 1897, he took credit for the apprehension of Professor Janus after receiving great assistance from the Tenth Doctor and Rose Tyler. He wanted to pass their names onto Queen Victoria. But the Doctor convinced him to cover up their involvement. (COMIC: Bat Attack!)
