A gang of yobs who wreaked havoc with a bag of onions in North Harrow were just moments from showering a baby in shards of glass.
The mindless teens pelted the vegetables at homes in Wood-lands, at 8pm on Friday, leaving three families with smashed windows.
One family targeted by the group were Ian and Julia Elmer, who had settled down in the living room having put nine-month-old Martha to bed, when an onion came hurtling through the pane of glass in their front door.
And while the crash only left the tot's pushchair showered in glass, had they struck earlier the consequences could have been tragic.
Mr Elmer, 38, said: "It was quite a shock when it happened because the amount of noise it caused was incredible.
"It actually sounded a bit like an explosion, so it was a surprise to walk through and see an onion in the hallway.
"Thankfully we had put the baby to bed. The panel shattered all over her pushchair and we spent quite a bit of time making sure we had cleared up all the little bits of glass.
"It just seems like a pointless and ridiculous thing to do and there was no way of knowing what kind of damage it might have done."
Although the cost of the double-glazed pane will be covered by the couple's insurance, they have been left with a boarded up a window and a draft to put up with in the current severe weather conditions.
He added: "Fortunately the cost of the new window will be covered because we have a crime reference number but we could have done without the hassle of having to sort getting a new window.
"It's just a shame because in the two-and-a-half years I have lived here I have never had any problems like this."
It is believed that the thugs had stolen the onions minutes earlier from a nearby supermarket and although the police were on the scene shortly afterwards no arrests were made.
