Upon the request of the commission, the Attorney General or the district attorney of the proper county or city and county may aid in any investigation, hearing, or trial under this chapter. The Attorney General, a district attorney of the proper county or city and county, or a city attorney may institute and prosecute actions or proceedings for the violation of any law committed in connection with, or arising from, a transaction involving a charter-party carrier of passengers.

(c) A peace officer may enforce and assist in the enforcement of Sections 5411 and 5412 resulting from a violation of Section 5371, 5379, 5385, 5385.7, or 5387, or more than one of those sections. A peace officer may additionally enforce and assist in the enforcement of Sections 5411.3 and 5414.5.
