Lost Birthday Found!

Bristol police announced this morning that they had found a birthday which had been missing for the past week.
Toddler Pixie H, who should have celebrated her birthday on July 23rd, had to delay festivities owing to the fact that her birthday had "gone astray". The police officer who recovered the birthday said that investigations were ongoing to discover whether foul play was involved. Later, Bristol Police Force issued the following statement:
"When the birthday was announced by one of the parents it was nowhere to be found. The birthday in question was recovered late last night and while it appeared to be in good shape doctors insisted in keeping it under observation overnight. It was returned to its owner this morning. We have reasons to suspect that the birthday was being held captive against its will. We have not ruled out the possibility that this was an inside job and we plan to continue with our investigation until we find the culprit."
Meanwhile, Honey H, the birthday girl's older sister told reporters that she was "happy" that her sister's birthday had been returned but that any efforts to track down the "wicked criminals" who had carried out the crime was "a waste of police time and public funds".
"We've got the bloody birthday back so let’s forget the matter." she was overheard telling one of the investigating officers.
Happy (Belated) Birthday Pixie!
