No. You didn't. You said "touched her" ... and you ranting in such general phraselogy is why ever increasing numbers of people will do nothing to help a child who appears to be in distress (lost, fallen over, whatever) in a public place because they fear some lunatic like you will immediately start shouting paedo, using violence and calling the police ...
Congratulations on your contribution to the society that your granddaughter will grow up to enjoy ... or not, as the case may be ...
