Business Secretary Vince Cable has warned that regulating payday loans creates a risk of "letting the 'baseball bat brigade' into this industry" - apparently referring to loan sharks.

There is evidence in both directions here. In the United States they have introduced caps on interest rates, they do seem to work.
On the other hand, we commissioned a study from the University of Bristol that warned about the dangers, if it is not done carefully, of letting the 'baseball bat brigade' into this industry.
