Where is it written about Veronica's veil?

Where is it written that Veronica gave Jesus a towel to wipe his face and that an image of Jesus appeared on that towel? Thank you.

The account of Veronica’s veil is taken from the apocryphal writing “Mors Pilati” (Acts of Pilate). For more information see:
