With regard to claims predating February 7, 2003, there is no indication when they accrued, and petitioners did not sufficiently set forth the manner in which such claims arose to allow respondent adequately to investigate and evaluate their merits ( see General Municipal Law § 50-e [a]; [2]; Brown v. City of New York, 95 NY2d 389). The conclusory claims of negligence in hiring, training, retention and supervision were likewise too vague to provide respondent adequate notice for proper investigation.
We have considered respondent's remaining contentions and find them without merit.
